Take this on your way down!G 10

This is found in story mode > Round 3A on the fourth level.

From the start of the level, interact with the caveman on the left a few times and then interact with the caveman in front of the "Gameboy" on the right to worship it. Then interact with the "Gameboy" and complete the jump mini game which will start up the running sequence. You will need to allow one of the cavemen to advance ahead of you prior to the last jump so he can give you a high five as you try to clear the final jump.
