Battle at Arlong Park

Arlong Park packs a whole arc into 926 pieces, from the shark-shaped fishman headquarters with Arlong's throne inside to the shooting gallery Usopp can take aim at. No longer at retail, and the pagoda is the standout: tap the top firmly and the entire structure collapses, then goes back together in seconds. Luffy comes with the arm-lengthening pieces for his Gum-Gum attacks, and there's a ketchup bottle tucked into the trees for anyone who knows exactly why that matters.
