Frogger 2: Swampy's Revenge is a console and computer game released in 2000. The game is part of the Frogger series, and the sequel to Frogger (1997), featuring similar 4-way movement gameplay in a 3D world. Unlike its predecessor, Frogger 2 featured a choice of different characters to play with in the game, and several multiplayer modes.

The playable available from the start characters are: Frogger, Lillie Frog, Tad and Treeby. There were also unlockable characters: Wart, Tank, Roobie and Swampy. Collecting all of the coins in a level unlocks levels in arcade mode. For example, collecting all of the coins in the first level (The Garden) unlocks the level "Toad Road." When you unlock all the tracks, then you unlock the hidden characters, and the game mode Mini Frogs. (Wikipedia)
