Sorry, that isn't very clear on the character sheet unless you look at the last of skills listing to note them and realize that is his circus skills. Those would be his entertainment for circus.
LOL. No. The whip wasn't learned for snapping at lions and such. :) Just an odd skill he learned and used it a bit in performance, but no animals and instead other participating players in performance it was used against.
