Trivia Contest of Velis Vel

Starting with you, each player may name a
creature type that hasn't been named. If they do,
they create a 1/1 creature token of that type
that's all colors. Repeat this process, but only
with players who successfully named a creature
type. Repeat until only one player successfully
names a creature type. That player creates a 2/3 Shapeshifter creature token with Changeling.
Uhh... Crocodile?
