The game uses single-screen side-view stages. Players jump around each level, blow bubbles to trap enemies, and then burst those bubbles by touching or striking them. Clearing all enemies advances the stage. Power-ups such as speed boosts, lightning, and bonus foods appear throughout the levels, and many stages reward careful positioning and chain defeats. Progress is level-based, with increasing enemy patterns and tighter platform layouts as the game advances.

Bub

One of the two playable dinosaur heroes, specializing in bubble attacks.

Bob

Bub’s partner, who joins the rescue mission and fights with bubbles.

Try to gather enemies on one side before bursting bubbles for safer clears and higher combo potential. Grab speed-up items early to improve movement and recovery. In crowded stages, focus on control rather than rushing; good spacing and bubble timing are more important than constant attacking. Learning enemy movement patterns is key to surviving later stages.

Tips and tricks

Plan your bubble placement so enemies bounce into each other or into hazards after being trapped.

Tips and tricks

Co-op play is easier when each player controls one side of the screen and avoids overlapping movement too much.
