I'd never seen them frogs before. When my boys had them octopusses (octopi) they worked pretty good the first dozen or so times but then they'd gather dust and lose their stickiness. After that they'd just fall on the floor.
I still think the engine is going to be way too much for the street but we're going to make it run on pump gas. Maybe if it does turn out to be unstreetable my son may end up putting the 512 in the Charger instead. I wish he had a desire to build a race car. I'd gladly build the funny for him and let him keep it. Maybe the big motor will still end up in it.
