Gooigi

Gooigi is a playable character introduced in the Nintendo Switch video game Luigi's Mansion 3. He is a slime-like duplicate of Luigi, created by Professor E. Gadd. Gooigi shares many of Luigi's abilities, including the ability to use the Poltergust G-00 vacuum cleaner.

Gooigi possesses unique characteristics that differentiate him from Luigi. He is able to pass through spikes, grates, and other hazards that would harm Luigi. This ability makes him essential for solving puzzles and navigating certain areas of the game. However, Gooigi is vulnerable to water and fire, which can damage or even dissolve him.

In Luigi's Mansion 3, players can switch between controlling Luigi and Gooigi. This mechanic is often used for cooperative gameplay, where two players can each control one character, or for single-player puzzles that require the simultaneous use of both Luigi's and Gooigi's abilities. Gooigi is summoned by Luigi using a special device called the Double Jump button, which requires Luigi to be in a safe location to create his gooey counterpart.

Gooigi's creation was a solution to allow Luigi to overcome obstacles that his normal physical form could not. His gooey composition grants him access to areas and solutions that would otherwise be inaccessible, adding a strategic layer to the gameplay of Luigi's Mansion 3. He is an integral part of the game's narrative and puzzle design, offering a distinct gameplay experience.
