MISTER BAT
by Emma S.

Emma writes,

"A fish-inspired bat! I also thought that a cool name for my bat tessellation would be Mr. Bat."

It's worth noting that bats aren't generally inspired by fish. It's Hollywood fake blood and real flying bugs that inspire bats. One rarely sees a bat with a fishing pole or even a couple of yards of fishing line.
