Editing Undodog

|species=Dog}}

'''Undodog''' (also formatted as '''Undo Dog''') is a helpful character first appearing in ''[[Mario Paint]]'', selectable as an icon in the bottom toolbox in the Art and Music modes. He is a tan dog that has pointed ears and a square box around his neck like a collar, meant to represent his selectable square icon on a game menu. The box surrounding his neck was black in the original ''Mario Paint'', but became white starting with ''[[Super Mario Maker]]''. His name is a pun on the word "underdog", and a portmanteau of the words "undo" and "dog", and, as his name states, he helps the player undo the last action performed.

Undodog debuts in ''[[Mario Paint]]''. His appearance in this game is that of a tan dog with a big head and a thin black box around his neck, like a collar, probably representing the outline of his icon. He will also dance and jump around at the bottom of the screen when the player is idle in the stamp editor or drawing board color selection. He will quickly run back to his original location if the player moves the mouse. If the player turns the game's music off and leaves it silent, Undodog will sometimes sneeze loudly. According to the instruction manual for the game, this is because of his allergies. <ref>''"When you click on the icon shaped like a treble clef, you can access a control panel that will let you change the background music. In this section, you can choose one of three different tunes. The fourth lever lets you work inside a quiet working environment. Don't be surprised, however, if Undodog's allergies cause him to sneeze occasionally."'' &mdash;''Mario Paint'' US instruction manual, page 19</ref>

Undodog reappears in ''[[Super Mario Maker 2]]'' filling similar roles and having the same appearance as in ''Super Mario Maker''. However, he also has a larger role in the game's story mode (appearing for the first time as a 3D model), providing [[Mario]] access to various jobs to help rebuild [[Peach's Castle]]. At the beginning of the story mode, Undodog excitedly jumps around and mistakenly presses the [[Reset Rocket]] button on the ground, completely erasing Peach's Castle. At the end, after the castle is entirely rebuilt, Undodog goes over to the Reset Rocket again and looks at it happily while everyone gasps off-screen. In the postgame, the castle is still standing, implying that Undodog left the button alone. Undodog can also be seen in the background of nighttime levels in most themes riding the Reset Rocket.<ref>Nintendo (June 12, 2019).
