Winglets: Fish is the 16th Winglet. The plot is often said to be the nuttiest plot of any book or Winglet in the Wings of Fire series.
In this winglet, fish take over Pyrrhia and guard against mind readers by eating skyfire. They have several other species under their command, such as walruses and penguins. They are stopped by in the end by rainbow gummy bears, the same ones who ate Mangrove in Book 13. Then,Whirlpool eats a cheeseburger and turns into a cow, which Clay eats but then Whirlpool turns back into a dragon and pops out of Clay's mouth. It is from the POV of Whirlpool.
