The Dolphins have continued their remarkable start to NRL life with a 20-14 defeat of Canberra 20-14 in Redcliffe.
In Saturday's other matches, Canterbury won for the first time under head coach Cameron Ciraldo with an upset 26-12 victory over the Storm in Melbourne, while the Sydney Roosters got past the Warriors 20-12.
After blitzing the Roosters on a dry Lang Park track in their NRL debut, Wayne Bennett's Dolphins showed they could do it on a soaking wet Saturday at their spiritual home.
They prevailed against the Raiders, despite trailing 12-0 during the first half.
Hamiso Tabuia-Fidow jumped on a loose ball to score before the half-time break, however, before the Dolphins gritted their teeth and defended early in the second term.
Finally afforded some territory, Tom Gilbert was awarded a try after jostling with Matthew Timoko to level the scores with 18 minutes to play.
Tabuia-Fidow then ran smartly from dummy-half and drew a professional foul from Hudson Young.
The back rower was sin-binned for the rest of the match and the Dolphins edged ahead by two points, courtesy of a Jamayne Isaako penalty goal.
But Dolphins halfback Sean O'Sullivan soon joined Young on the sidelines when he was sin-binned for a controversial hit that was deemed late and high on Corey Harawira-Naera.
Yet the Dolphins had the final say when teenage five-eighth Isaiya Katoa offloaded to Tabuai-Fidow for his second try to send the soaked 10,000-strong crowd into raptures.
They became just the third team, after the Brisbane Broncos and Melbourne Storm, to win their first two premiership matches.
Canberra's Jack Wighton was everywhere in the first 25 minutes, touching the ball 14 times and also leaping to dislodge Isaako of possession as he lunged for the corner.
The Raiders five-eighth had already crossed himself, wandering to the right edge and surging over to break the Dolphins' defence after some sustained pressure.
The visitors found space down the right 15 minutes later, with Nick Cotric's converted try making it 10-0.
Jeremy Marshall-King was then sin-binned and placed on report for a hip-drop tackle on Corey Horsburgh.
But the Dolphins scored while a player down to breathe life into the contest. Sebastian Kris fumbled a Sean O'Sullivan grubber kick, allowing Tabuai-Fidow to plant the seeds for the home side's incredible comeback.
Bulldogs stun Storm
Canterbury has turned up the tempo to shock a listless Melbourne Storm on their own turf.
The Storm were missing injured star playmaker Cameron Munster but his absence was no excuse for their embarrassing defensive effort.
With a free-flowing attack, the Bulldogs – under first-year coach Ciraldo — were unstoppable in the first half to lay the platform, scoring three tries to surge to a 16-0 lead.
The Storm's usually rock-solid defence crumbled with the home side tallying a massive 31 missed tackles in the opening 40 minutes, before ending the match with 49.
Despite stern words from coach Craig Bellamy there was little response after the break with Bulldogs winger Jacob Kiraz scoring his second for the night in the 44th minute.
And they were in again five minutes later with a soft try scored by centre Jake Averillo to extend the lead to 26-0.
With Tyran Wishart replacing Munster, the left-edge of centre Young Tonumaipea and rookie winger Grant Anderson was in disarray.
Tonumaipea earned a spot in Bellamy's bad books midway through the first half when he ran the ball on the last tackle and was then sent to the sin-bin after tackling a player without the ball.
The Bulldogs made the most of his temporary exit, with Kyle Flanagan and Reed Mahoney busy orchestrating the attack.
Kiraz got on the outside of Anderson and then ex-Storm flyer Josh Addo-Carr celebrated after crossing in the other corner.
It looked like former Penrith back rower Viliame Kikau may have have added their fourth for the half, but it was denied by an earlier knock-on.
Fired-up Storm prop Nelson Asofa-Solomona took matters into his own hands to barge over to put his team on the scoreboard.
But Asofa-Solomona was forced off soon after when his night ended by a knee injury.
With the Storm's attack finding some rhythm, Jahrome Hughes then ran off a Harry Grant pass for a 57th-minute try to give the Storm some hope while the points dried up for the Bulldogs.
Kikau was also sent to the sin-bin for a trip in the final minutes but it did not take the gloss off a well-deserved win that was the Bulldogs' first of the year.
Roosters get home against Warriors
Luke Keary and Joseph Suaali'i have offered a glimpse of the new-look Sydney Roosters' left-edge potency, as the Tricolours survived a late scare to hold off the Warriors.
Dominant for most of the match and with enough chances to ice the result early, the Roosters were forced to hold through a nervous late period at Sydney Football Stadium.
But after the Warriors blew three chances of their own while down 18-12 late, Sam Walker sealed the match with a penalty goal for an escort with five minutes to play.
There were some concerns for the Roosters, however, with Suaali'i placed on report for a late hit on Charnze Nicoll-Klokstad, and Brandon Smith suffering a rib injury.
Right-side winger Jaxson Paulo bagged two tries in the win as the Roosters went some way to silencing their critics after a shock-opening round loss to the Dolphins.
However, it will be the promise of things to come down the Roosters' left edge with Keary at five-eighth and Suaali'i at centre that will excite the club's fans most.
The two combined for a brilliant try to make it 18-6 midway through the second half when Keary dummied to his right and then passed to his left to put Suaali'i into space.
From there the teenager bust down field and eventually found Walker looming up in support to score.
It was one of two times Suaali'i was able to get into clean air in the second half, with Walker putting him into space again minutes later through the centre of the field.
The ball ultimately went to ground when Suaali'i attempted to find James Tedesco, in a moment that summed up the Roosters' afternoon.
They looked in control from the outset when Tedesco put Paulo over in the fourth minute and took the ascendancy again in the second half when Joey Manu helped the winger over for his second.
But with Nicoll-Klokstad and Jackson Ford off with concussions and Josh Curran a hip injury, the Warriors threatened to pull off an unlikely upset.
Marata Niukore got the visitors back in the match at 18-12 when he broke through and helped Addin Fonua-Blake cross under the posts with 18 minutes to play.
Then in the space of five minutes the Warriors failed to make use of a Wayde Egan bust, had Edward Kosi play the ball to no-one when on the attack and watched Dylan Walker drop the ball metres out from the line.
It proved costly when Walker iced his late penalty goal, and helped the Roosters join the Warriors with a 1-1 win-loss record after two rounds.
