A memory from my childhood.
Mystic Marsh was one of my favorite levels in Spyro 2: Ripto's Rage; for the zany-looking wildlife, that one fun challenge where you collect things for the Professor, and not to mention the glitch that lets you fly around in the air.
Also, food for thought -- that little duck is a rubber duck, so how can it swim???
