Here comes Grune the Ghost Warrior! Can you help the ThunderCats defeat him? Hundreds of years ago Grune the Destroyer swept across Third Earth, looting and burning everything in his path. No one was a match for his terrifying power - not even the devil-priest Mumm-Ra, who finally trapped him and sealed him in a tomb. But now someone has opened the tomb, the ghost of Grune is on the loose, and he's just dying to pick up where he left off! The mighty ThunderCats must find Grune and put him back in his tomb, and it's up to you to help them! But beware - enemy Mutants, poisonous bats, and vicious gargoyles await you as you find your fate!
