This unspeakable horror is called... wait for it.... Ichiroach Suzuki.
Let that simmer for just a second. Are you completely creeped out yet? Good.
Ichiroach is just one of many crimes against nature perpatrated by something called the Zooperstars, a group of traveling mascots that include Peyton Manatee, Deion Salamanders and Ken Giraffy Jr. To make this all even more terrifying, I do need to mention that these are inflatable costumes.
Found at Deadspin, and I will never, EVER truly forgive Will for this. More general creepiness after the break.
