Twilight Princess Help-forest temple?

ok i beat the baboon an got the boomerang & immediately saved & quit afterwards cuz i was bored. problem is when i continued playing later i was back at the beginning of the dungeon an to cross the big gap to get back to the baboon room i need the 4 monkeys but theyre not there anymore & theres now no way to get across. i need to get to the otherside to free a new monkey or else i cant get to the boss room at the end. if anyone knows what im talking about an knows how to get the monkeys back to swing me across the gap, ur help wud be greatly appreciated. lol this sounds like a ridiculous problem to have an im probly jus doin somethin really dumb which ill later realize, but yea still help wud be appreciated
