To answer your question, yes, they do burrow. However skeletons are more fond of constructing a webbed hide near burrow entrances rather than digging. They will create extravagant webs packed with leaves, moss and substrate rather than dig a hole. Though some do dig on occasion.sorry ask out of turn but, do these burrow?
Great choice. They are my favorite T's.mmmmmm......... i think i want one. thanks
