Gaddget

Gaddgets are miniature toys invented by Professor E. Gadd in Mario Party Advance. There are sixty-one Gaddgets. They can be earned by completing quests in Shroom City, winning Bowser's minigames, and exchanging coins for them (with the exception of the secret Gaddget, Toad Force V).

Gaddget is a portmanteau of the surname "Gadd" and the word gadget.
