Egg #111: More Student/Teacher Relations

Egg #111 is a return to the series 'Help! My teacher is an animal!' The premise is still a bit baffling to me, seeming to be a situation where this kid's teachers shapeshift from human to animal and he has little holographic clips that switch between their forms. The first I got in the series depicted a bulldog/gym teacher. This appears to be a male teacher/frog cross.

It's just a big sticker that goes on a simple flat clip so no difficulty at all in assembling, even for me and my sticker dumbness.

I would appreciate more backstory on this but I fear I've figured out what there is to know about it already.
