Spungs are baby-like creatures that operate munkles on Snohmun. The munkle is a suit that helps the spungs perform heavy lifting. Spungs live off baby food and never grow up, however they have incredible spatial awareness for a toddler. Who else would you want stacking vehicles in your ten storey garage? Buzz Aldrin? Maybe, but fitting Buzz in a munkle would practically be impossible, so a buzzmunkle is never going to happen.
