A Wiggler is an enemy in the Mario series of games. They look like oversized yellow caterpillars that squirm around in maps- but once they are disturbed, they turn fiery red, and start charging instead of “wriggling”. Wigglers were introduced in Super Mario World, and later came into the Mario Kart series in Mario Kart: Double Dash!!.
In Mario Kart
The likeness of Wiggler makes its first Mario Kart appearance in Mario Kart: Double Dash!!. Borrowing its green color from Super Mario Sunshine, long Wiggler-like buses known as Wiggler Wagons appeared as part of the traffic in Mushroom Bridge and Mushroom City. Unlike the cars and trucks, which simply made racers spin out, Wiggler Wagons flipped racers over. They are also immune to all Items and attacks; if a player with a Starman hits a Wiggler Wagon, they will simply ricochet back.
In Mario Kart DS, Wiggler is the final boss on Level 7 in Mission Mode. A racer must beat Wiggler in a race on Mushroom Bridge by collecting Starmen/Mushrooms and staying at the fastest rate possible. Wiggler gets faster after each lap has passed; on the last lap, Wiggler gets angry and goes at almost insurmountable speed.
In Mario Kart Wii, two big Wigglers appear in Maple Treeway. Bumping into them pushes racers back, making them huge obstacles when they jam the preceding branch. A competition on Wario's Gold Mine took place with a Wiggler. Players had to race it and like Mario Kart DS, and Wiggler got angry on the last lap.
Wiggler is featured as a new playable character in Mario Kart 7 along with Lakitu, Metal Mario, and Honey Queen. His weight class is Cruiser, though his voice sounds like a little girl. When hit with an item, he will turn red for a few seconds, although no speed is gained, just pain. Two Wigglers can be seen in the aforementioned track, Maple Treeway.
In their first appearance in Mario Kart, Mario Kart: Double Dash!!, Wigglers were green caterpillars, opposed to the recent yellow ones. They had four body sections and a head. Random red circle patterns appeared on their body. They had orange legs with eight shoes (he's gotta be pretty fast). There was a white flower on his head, and he had a red nose and a smiley face (until you make him mad!).
The new Wigglers are now yellow, but they still retain the same features and characteristics, but just in a different color. They now have orange spots and legs with pink shoes. The flower on top of his head is still white, and his nose is now brown. Also, as a driver, Wiggler now has hands with white gloves, because it is hard to use a steering wheel without hands.
Caution: it is advised not to make these caterpillars mad; they react VIOLENTLY! They turn a dark red and have a vicious, angry face. As obstacles, when they are mad, they gain speed and power. Keep that in mind when trying to beat the Level 7 boss on Mission Mode in Mario Kart DS.
