Brikki the Timid Monster is afraid of breeding bacteria on kitchen sponges. She makes sure no one leaves them buried under all the dishes in the sink where they are sure to stay damp and moist. If she does find any wet sponges about, Brikki just pops them into the toaster for about two minutes.
Skom is afraid of kitchen fires. Namely those started by someone putting sponges in the toaster. It doesn't matter if they start because the moist sponges short circuit the appliance, sending sparks shooting positively everywhere but most often to the napkin holder, or because the sponge stays in too long and bursts into flame. Either way he's seen more than his fair share of sponge-induced kitchen blazes; Skom avoids the kitchen these days.
