Mice vs dinos? It's no contest. Unless you're talking HEROMICE, of course. Don't make the mistake of thinking being a Heromouse is all about being famous and wearing a nifty green leotard. OK: we'd be lying if we said Geronimo doesn't enjoy that part of the job. But what's the other part? Facing DEADLY DANGER! So when super-scary dinosaurs attack Muskrat City, the Heromice are onto it. But HOW exactly will they fight back? Thank goodness Geronimo is strong, invincible and fearless (well, almost).
