What is super mario galaxy 2 switch?

Unfortunately, as an AI language model, I do not have information about Super Mario Galaxy 2 switch since it does not exist as an official game released for Nintendo Switch. However, Super Mario Galaxy was released for Wii and then later on re-released for Switch as part of the Super Mario 3D All-Stars collection that also includes Super Mario 64 and Super Mario Sunshine. Super Mario Galaxy is a 3D platform game developed and published by Nintendo. It was released in 2007 for Wii and has received critical acclaim for its gameplay, level design, and graphics. The game follows Mario as he travels through the universe, exploring various planets, and collecting Power Stars to save Princess Peach from Bowser.
