To achieve 100% completion, you must find all hidden Spatulas and Photos in every level. Use SpongeBob's 'Spin Attack' to defeat robot clones, but switch to Plankton when you encounter small vents or electrical panels. In World 2: Kelp Forest, keep an eye out for the 'Tank' transformation—this gadget allows you to blast through reinforced walls that hide the secret Golden Spatula. Remember: Co-op mode can be unlocked after the first level, allowing a second player to control Plankton's inventions directly!
