Cinema 4d character rig & walk cycle needed

Hi. I have modelled a couple of characters, a snowman and a penguin, which need rigging in cinema 4d. I also need a simple basic walk cycle for the snowman too. Attached is a rough test render of the models as they are. The face does not need rigging. The arms just need shoulder, elbow and wrist for both. Legs need just hip and knee (perhaps, based on your judgement - they are short). Is something you might be able to help with?
Thanks
