Seedpod

From Srafopedia

While having no proper mulefa name, the seedpods play a vital role in mulefa life. The mulefa use seedpods as wheels by hooking their front and back legs into the indent where the seed was attached to the seedpod tree. Using their two lateral legs, the mulefa then can push themselves on the seedpod wheels. Steering is mainly an act of leaning. Seedpods come from Seedpod Trees.
