Toad Rage by Morris Gleitzman

Limpy can't understand why humans hate all cane toads so much - they even squash them with their cars. He is determined to save his own family from ending up as flat as place mats. He sets off on a 'mucas-chillingly dangerous and wart-tinglingly daring journey' and risks everything to make humans see that cane toads are really very nice.
