guide the dinosaur to level 5 win out being touched by the Yeti. If you click the dinosaur it will restart to level one, and on the boss level click arrow keys to shoot a fireball. when you hit the fruit salad you will win the game PRESS GREEN FLAG WHEN READY. When the Yeti is at the level checkpoint you will have to wait until it passes over the spawn point.
It took me about 3 hours Thanks to my friend for suggesting a boss level
