Spore Hero Arena Lilypadian Help

Lilypadian is the 6th planet i believe. I have two blue medals from the planet already and i raced the monster around his track. I dont know how to get to the other two blue medals. the paths on the map are blocked by a giant boulder looking thing and the other path is blocked by a fruit shaped thing. the paths im referring to are near the holes where the bugs come out of across from the guy u race. Can anyone help me ???

I am having the same problem. :(

ugh it sux. im wondering if this is a problem with the games programming though. im certain that ive done everything i can do. i think ill start a new file and see if i have the same trouble. im waiting for a guide to come out because i have to finish a game once are start it.
