Mollusk Whistle

The Mollusk Whistle is a mount-summoning item. It can be bought by the Zoologist for 20 after the world has 25% of the Bestiary unlocked (130 entries out of 520). It will summon a rideable flamingo Mount that travels 38 miles per hour when used. This mount allows one to swim in water, and when swimming the player can dive by holding down. Interestingly, the mount bobs to the surface when the down key is released, and if deep enough, the mount will get launched out of the water into the air.
