Because soft surfaces such as beds and couches cause their bodies to pool inward, goo ponies prefer a hard surface as a bed so their body can spread out and relax. Partners of goo ponies who would prefer a soft sleeping surface will have no problem accomodating them: because they themselves are soft and are naturally attracted to sources of heat, their body will provide both a soft place to sleep and their habit of snuggling around their partner’s warm body will provide a nice substitute for blankets.
