A very simple image can really grab one's attention. This would make a great emoji, imo. :) Another hero from the cover.

I'm a huge Penguins fan: the Madagascar movies, Penguins movie and short film, and all eps. of the TV series. Skipper, the manliest of penguins, is my favorite. Maybe one of he funniest voices in animation, its seriousness contrasts w/his silly appearance.
