In Donkey Kong 64, one of the minigames is "Beaver Bother" where you try to herd beavers into a hole. I've tried this a whole bunch and am having a really hard time beating it.
My strategy has been pretty much to just run up to the beaver closest to the hole and spam the B button, which the tutorial says is supposed to scare them. I don't see any visible evidence that it is working. What usually happens is the beaver will just stay near the hole, but not fall in, then go to either the right or left away from the hole. I've tried shoving the beavers in as well, but that doesn't seem to work. Jumping (A button) seems useless to me, so I haven't used it.
What is the trick to beating this minigame?
