A question came up in a game recently. Can a Druid use Wild Shape to transform into a parasitic animal and thus occupy the same square as the host, as well as smuggle the Druid into some other place?
How would you run it if a Druid Wild Shaped into a tapeworm? Could she use that to sneak past some guards inside another person? The general rule is that if they are inside another animal and de-wild shape, they just appear next to the first creature rather than making it explode by resizing inside it, so I am not so much concerned with how the end game would work out, but whether or not it would be allowed, how combat might work, stuff like that. Thoughts?
