Wobbly Bobbly is Kat and Ana's multiplayer mode in WarioWare, Inc. Mega Party Game$. It involves the players sitting on turtles and trying to stay on them. Firstly, the players play a multiplayer microgame. The winner of that is given a single player microgame challenge. If that player wins, its opponent or opponents are given another turtle of the same size. If that player loses, that player earns itself a smaller turtle. After that, Patience Time begins, in which the players remaining have to balance for a certain amount of time. If the multiplayer game is won by a player who has became a turtle, the game skips to Patience Time. The winner is the last one to survive on the turtles. If there is more than two players, players who have already fallen off their turtles can become turtles themselves and try to knock over the remaining players.
If there is a tie in this mode, the players will play a final round to determine the winner.
