I want slimes...(´；ω；｀)

To desire slimes is a wish full of ambition! Gather anti-Red attackers like Cat Island and Super Express, and aim for the Professor with the Thunder Cannon! Take my advice to heart and seize victory, Gau!

Are you talking about countermeasures against the Professor (hitting from a distance or forcefully blowing them away)? It also depends on the characters you have.

If you have it, I recommend Comboes. It's very effective against the Professor and you can force your way through. However, if you use Comboes, you need to cover yourself so you don't get cursed by the ancient dog.
