Isthmus Be the Way is a Co-op minigame in Super Mario Party. It is a pun of the phrase, "this must be the way" and "isthmus". If one starts to wave the Joy-con before the bomb is passed to the player, an easter egg will appear, that character will also wave.

Ending[]
The Toad puts the bomb in the cannon which shoots a firework and all fireworks also appears.
