A little guide showing the Gromble's various transformations in the game. His strategy initially involves getting the Fear Meter up so he can become a significant threat. Try to get him to level 4, you can say that at that level....
I made up the scarier forms. Nobody knows what Gromble looks like when he performs a scare (the only one he did in-show was done off screen and you could only see his shadow) so I decided to be creative with it.
