Longer legs on the toads is not the only evolutionary effect going on here.
Snakes in Queensland (where the toad was first introduced) have increased in length by 3-5% since the toad arrived. The theory is that the longer the snake, the greater the body mass, the better it can handle the toxin.
I also remember reading somewhere about smaller heads in relation to body size thus limiting the size of the toad consumed and the amount of poison ingested.
