Our friend Wilbur got stuck in level 4-5, can you help him out?

Ice Age: Level 4-5

Sorry, but stuck again . . . This time right at the beginning of level 4 (gaseous cave) part 5. After going to acorn #1 and getting on that shelf, I have tried moving the larger rock one way, then the next . . . I see the need for the two stalactites which need to be lowered and then moved to be able to move the smaller rock which is on top of larger rock . . . Unfortunately, I cannot get rid of them. Yes, I am going around in circles! Help please.
