I found from my week of addiction to the game that most of the levels actually have triggers in them that set up other events. So if you don't do one thing something else will not happen. Like in the egg toss you have to get X many points until the moles pop up, then you have to get all the moles to get the board with the moles in it to come up, after that the scarecrow (get all the crows) then the pigs, or something like that.
Specifically I'm not sure what you have to do to trigger the bee's, I think I beat it by luck!
On the ring toss, you have to wait for the attenna to come up, then you shake the wiimote until the flying saucer makes it to the top, then you have to get a ring on it, which will launch the saucer and the four rockets.... Glad it's not complicated!
