Are Kre-O toys transforming toys? I haven't looked, but there's probably already a long thread about this, arguments done and dusted, two opposing camps hold to their valid opinions, etc. Personally, I think the block models transform as much as a Lego model can be 'transformed' from a crane to a car to a plane for example. Haven't thought about it much, but that's probably why I have instinctively chosen not to go for what I consider non-transforming toys (includes Kre-O, and definitely stuff like Robot Heroes). But you might ask me what about stuff like PE Motobot (Arcee) where you have to reassemble whole parts of the figure? Too much for one thread to handle...
Now... the mini-figure Kreons are an interesting category. They do kind-of transform, so I guess I should've included this guy. If you would have voted him your favorite Springer, let us know!
