Ep 4. Sphere

Will thinks that he should be the hero, and drags Nick along with him to infiltrate the enemy's base and steal some of their weapons. At the same time Joey, having successfully dropped off his grandmother at the shelter, heads toward Professor Denton's place to get more information. On the other hand, Kogorr starts attacking with a giant sphere. And what's more, it's started rolling straight toward the shelter where Grandma and Lina are! Joey and Heroman head out to face it and stop its advance somehow.
