I can imagine that too! The one in the wreath did push one semp off with his butt as he was burrowing down but thats the only damage toads have done. Now squirrels and gophers are another story with my containers.
I have a couple of small glass ladybugs in my semp containers and couldn't figure out why they always ended up laying outside the pots. Yesterday I finally figured it out - the birds were trying to eat them. Hope they didn't damage their beaks!
