Treat Kenya Tree like a small plant. Small pair of scissors and shape it however you want. It doesn't like being cut, but it recovers quickly. You can basically prune them like you would a plant.
It really depends though. If the Toadstool doesn't like movement, then it'll probably be annoyed and at a disadvantage, because Kenya like to shift their branches around. The pace is extremely slow so I doubt it'd cause an issue, but you never know. The Toadstool could be fine with it, or it may not be.
