Electroplankton Trapy is a DSiWare video game released in 2009. It costs 200 Nintendo Points. Electroplankton Trapy is the same game as the Tracy mode in Electroplankton for the Nintendo DS. Virtually nothing has been changed, despite the omission of the nine other game modes (which were released separately on DSiWare).
NintendoLife gave the game a disappointing 4/10, stating that the game is a bit too easy (this is understandable, however, since in Electroplankton Trapy was the first listed "instrument"). In the end of the review they stated that of the five Electroplankton games released on November 5, this was easily one of the worst.
