Through a series of activities on the Planet's different islands, players earn clues that ultimately help them identify the guilty Mumblers. In Mumbler Maze kids use arrow keys on their keyboard to direct Mel around a maze collecting gems and avoiding Mumblers. Once complete, they must rearrange scrambled words and punctuation to create a readable sentence. In Geyser Valley, kids fire balls from the cannon into geysers. On level one, each ball has a number on it, and kids must fire the numbered ball into a geyser whose word has that same number of syllables.
Later levels have players forming plurals, finding synonyms, and more.
In Volcano Drop, the object of the game is to get down the mountain before the volcano blows. Bridge Puzzle requires children to spell words several times using their keyboard as they slowly rebuild a bridge for the Blaster pals. The first time they are confronted with a new word, they are given its spelling in full. Then, letters are dropped, and finally kids must spell out the word without any clues. There are 45 Mumblers to catch in all.
