Looking at the design of how the creeper is built, it's creepy. I mean, making a new custom brick for that when we have other bricks that could do the same thing? (LEGO isn't much of a system anymore, it's now pre-made toys discouraging imagination... )
Seeing how the legs are attached and permanent, you could animate them like people animate minifigure short-legs. Hopping, sliding, wiggling to and fro. Or, you could build a new one using pre-existing bricks (like the one I built a second ago). (Not the best, but a proof of concept. I'm better with I'm building with real bricks rather than LDD)
