Look closely at the pig with two arms in Jolly Roger Lagoon. He will drop his tube and his underweae will be showing. If you go in the Temple Of Fishes there will be another pig and his name is Chris P. Bacon (crispy bacon).

On the fire side, if you take the snowball from the icy side you can cool down the hot water at the very beginning and give it to the pigs in Jolly Roger Lagoon.
