In this game based on the episode "Make Believe It or Not" where Goo imagines the Evil Space Nut-Boogies, the player controls Bloo using the buttons on the Nintendo DS console. Bloo can jump and fire spit wads from a straw. The main objective of the game is to rescue Madame Foster who has been kidnapped by Space Nut Boogies. To do this the player must earn the cooperation of different characters from the television series by performing tasks for them in order to gain their help. Throughout the game the player must also find eggs laid by Coco which contain Coco cards. Coco cards allow players to view pictures they collect in their scrap book, which can be viewed from the pause screen. The gameplay is not similar to its prequel, as it is in 3-D.
