A1: He's not that hard. there are two trees on each side of the bridge with the vine to swing on. all you do is a running head slam on the tree (hold down o circle button) after you hit the tree the king will fall down from the bushes or tree from above right next to you and you simply attack the crap out of him using square button mainly or throw in a couple of roll hits or jump then hit circle hits.. I mainly used square attack and then one roll attack,then square attack some more,until he jumps back into the tree. cross bridge to the side he is on again,but this time he has blocked the trees with metal bars with a small monkey protecting each side,do a roll attack to stun the monkey,you'll see stars around it's head as it is useless and dazed,then simply hit square to kill the monkey. the bars then vanish and you can now do the running head slam again to knock the baboon king from the tree again,depending on which side of the bridge he is on of course. (he has to be on the side of the bridge where the tree is,the one your slamming into for him to fall by you so you can attack him. so ya do that and he should already be halfway dead by the second time he falls from your first attack. so slam the tree with your head,he falls,square attack him a few times,quickly do a rool attack or a jump and dive attack then more square attacks and he should be done for and dies really quickly after the second attack.
it seemed to me he gave up hitting on me and let me beat the crap out of him the second time I made him fall... he's not too hard. Also it helps to replenish your banana life bar while fighting him,to also help you beat him and other levels and bosses. I have not found any god modes to make you invincible,but you can replenish your banana health bar by pausing game quickly before you die,or have one banana health bar left,and go to cheats to type in the word Bananas,once you do this you will hear a confirmation monkey like sound,so you know it worked,u go back into the game,and wall-a! your health bar is full again... which makes it even eaiser to defeat this baboon king and other levels. I am on level 5 as we speak,which seems to be a fun level. some levels dont even have a boss,which is good. it's a pain in the butt to have to go back each time and type in bananas to replenish your health bar,but it helps you beat the levels and bosses and it's better then starting over. i'm sure there are more codes and I have tried many to try and find them,with no luck. it's not a bad game really,i mean I hate it,but I still wanna try and beat it for some reason,even tho I wish to smash it also... of course I would hate it more had I not found this replenishing code. ya need it to make it a tad more fair on your part to even get by some of the levels... just make sure you watch your banana health bar closely, if your down to one or two bananas? go to option screen,hit cheats,type in bananas,and you will replenish your health bar. it's the only way to have an edge.

the first two bosses are easy to defeat with this cheat.
baboon king is easier then the first,he kinda gives up after the first attack,and you can really pumble him,but just make sure you keep an eye on your health meter,in case he gets lucky,ya have to go out each time and type in bananas to fill your health bar,every time. which sucks. but it's all we got,so far...... I am playing on playstation 2,it should work for wii too.
