Acting on Dagur's advice, the riders have to strike Viggo's dragon auction, which is heavily fortified and open to only the wealthiest Vikings.
Tropes:
- Becoming the Mask: Snotlout gets way too into his "Sir Ulgerthrope" disguise, and hasn't stopped acting by the end of the episode.
- Beleaguered Assistant: Gobber has to pretend to be one as part of Snotlout's disguise. He ends up genuinely being one because Snotlout lets pretending to be rich go to his head, to no one's surprise.
- Beware the Silly Ones: The dragon hunter mooks laugh when they realize that fat, lazy Grump is part of Gobber's escape plan. Unfortunately for them, Tastes Like Friendship is in play, and Grump curbstomps them when he gets serious.
- Bittersweet Ending: The attack on the auction is a success and the captured dragons are freed, dealing a heavy blow to Viggo's plans, but the gold used as part of Snotlout's disguise is lost, which was Berk's entire reserve of gold.
- Bling of War: Snotlout has a gold helmet for his rich Viking disguise.
- Brilliant, but Lazy: Ryker claims that Grump can chew through the dragon proof metals. While that does come in handy later, the audience already knows that Grump is a Lazy Bum, so no wonder the dragon hunters have him in captivity. Heck, they just let him walk around loose in their base, eating all the scrap metal he finds, believing him to be barely a threat.
- Call-Forward: The special guest at Viggo's auction is wearing the crest of Drago Bludvist.
- Fakin' MacGuffin: Hiccup's attempt to retrieve Berk's gold at the end fails because Viggo switched the chest out for an identical one full of rocks, and tricked Hiccup into risking his life for that one.
- Fattening the Victim: Since no one is likely to buy him, Ryker would rather eat Grump.
- Paper-Thin Disguise: Snotlout's disguise is to dye his hair blonde and deck himself out in bling.
- Tastes Like Friendship: Gobber wins Grump's affections by feeding him rocks and scrap metal.
- This Looks Like a Job for Aquaman: Snotlout has to be the infiltrator, since he's the only one the dragon hunters have never personally captured or fought.
- Unexpected Character: Unlike Skullcrusher, whose presence was part of the plot description in Crushing It, Grump debuts with almost no fanfare.
