"What are these confounded contrivances anyway?" Caramon grumbled, glaring at it. "Some type of animal dwelling? I've heard tell of squirrels without tails who live in homes like these upon the great flatlands of Estwilde." He eyed the structure that was nearly three feet tall and just as wide, and shook his head. "But I'd hate to meet up with the squirrel who build this!" (Part III, Ch. 8)
Sadly, the potential magic was ruined by denying the D&D squirrels their due. Missed opportunity here, as having tailless squirrels building large structures would have been much more exciting than some dwarf tribe. Squirrels>any type of dwarf, after all.
