Pitfall: The Big Adventure Requests

i cant get threw the cavorn. ive gone down all 3 ladders and gone threw the sand hole, beaten all the porkipines. ive jumped off the side of the cliff toward the 2 things of boxes that swing back and forth but can't figure out how to get past the level. ive been trying for 4 days already if someone can help plz email me at hidden_underneath@hotmail.com

We keep seeing shaman that we can't get to because they're too high - one in the Turtle Monument and another in the Renegade Fort. Does anyone know how to reach the shaman?
