Bonsai Barber/YMMV

• Genius Bonus: Cutting Charles B. Foster's hair with Strawbinski's gravity device in place makes Charles comment on how "I spent most of my childhood this way up." Likely to make you go "Huh?" unless you've seen a banana bunch on the plant, in which case you'll see that are the bananas are, indeed, upside-down from the way we normally see them.
• That One Level: Charles B. Foster is a lot more difficult than the other characters to cut, probably due to his weird branch structure.
