Yenkara

Mystical creatures of legend, the Yenkara are large, pink monsters with wings who inhabit the isolated and beautiful Valley of the Yenkara. The only known Yenkara to ever be captured and brought back to civilization was caught by the evil poacher MacKnee, and was returned to the Valley of the Yenkara after being adopted and named Henry by Molly Cunningham. Normally, Yenkara are small and harmless creatures, but when they get wet their sponge-like body absorbs all the moisture and causes them to grow ten times their normal size. In this state, they are still gentle and friendly creatures, but their massive size and strength makes them inadvertently troublesome.
