Playing LEAPFROG EXPLORER LEARNING GAME: DISNEY PHINEAS AND FERB is almost like watching an episode of the show of the same name, minus a few key characters. In it, the boys decide to build a water balloon launcher that they can drive around. At the same time, Dr. Doofenshmirtz has created a similar machine that shoots rotten food. Throughout the game, the boys are upgrading their machine and testing it out on some rogue robots. When they aren't looking, Agent P, aka Perry the Platypus, borrows the machine to battle Dr. Doofenshmirtz and his food-slinging robots.
The game has six levels to complete with increasing difficulty, each containing educational mini-games. In the mini-games, kids build the blueprint for the machine using Tangram-style pieces, collect parts for the machine while fighting off robots, complete simple electrical circuits in order to open doors to collect the parts, test the new machine while fighting off robots, and complete \"contraptions\" that allow Agent P to get where he needs to go. While fighting off robots, kids can earn power-ups by completing math problems. The game has two difficulty levels. On more advanced levels, the puzzles are trickier. As an example, on the easy level, the tangram puzzles show the outline of the pieces. On the harder level, there are no outlines.
