Join Stevie, the world's grumpiest slug, in slug self-esteem class to find out why you shouldn't squash these amazing creatures! His name isn't "Yuck!" or "Ew!", it's Stevie, the world's grumpiest slug. It's time for slime.

Being called rude names by humans has made slug Stevie super-grumpy, so his mum sends him to Slug Self-Esteem Class. Stevie discovers why he and his slimy kin are actually kind of amazing: they can regrow bits of themselves, their slime is liquid crystal and their climbing skills are better than Spiderman. The first in this series about creatures humans often try to squash!
