At the end of the first adventure platformer, Jim intends to win the heart of the princess he has freed, and when everything seems to be getting better, the princess is kidnapped by the devilish Psy-crow, who himself intends to marry her and thus gain power over the entire galaxy. To prevent this villainous plan, a journey through numerous worlds is ahead. Jim uses his amazing abilities and awesome weapons like Mega Plasma Gun, Three-Finger Gun, Barn Blaster, Bubble Gun and Homing Missile. His bosom friend Snott helps the hero in every way he can, riding on Jim's back and acting like a parachute; helps Jim to slowly descend or, acting as a Snott Swing, to cross wide ravines at the right moment.
A common earthworm named Jim leads the daily life of an earthworm, traveling all over the earth avoiding crows and doing other worm-like things. Jim suddenly found a very large ultra-tech-indestructible-super-spatial-cyber-suit by a lucky chance. Suddenly, the ultra-high-tech space particle suit began interacting with Jim's soft worm flesh. Evolution happens at the speed of light. Jim soon realizes that he is under the control of the suit. The gameplay is similar to the first game with Jim jumping and running around the levels. There are 5 weapons in total, slightly more than in the original game. New characters also appear - Princess What-Her-Name and Psy-Crow.
