Jet Tank One
The Jet Tank One is an invention created by Penny, and is her main gameplay mechanic in WarioWare: Get It Together!
The Jet Tank One is first unveiled when Penny finishes building it in her lab. While giving it a test run, she receives a call from Dr. Crygor. She quickly flies to WarioWare, Inc. using the water cannon and enters the game. When she arrives at Wario's crew, she combines the Golden Beehive, Golden Toilet Paper Roll, and the Golden Holey Mug that the crew had collected into a Golden Watering Can. After she fills the Golden Watering Can with water, it floats towards a nearby toilet and waters it, causing a massive beanstalk to grow from the toilet hole.
The Jet Tank One has a different form of control from other flying characters. By tilting in a direction, Penny sprays water toward that direction, with the recoil of the water cannon pushing her the opposite direction. Pressing 
allows her to hover in midair, which negates the recoil of the water cannon. Pressing again cancels the hover, allowing her to move again.
The Jet Tank One can affect microgames that involve water, fire, or heat elements. These microgames include the following:
- Foggy Glasses: Penny can spray water in the food containers to put out the steam.
- Sanitation Station: Penny can wash the hands without turning on the faucet.
- Face Wash: Penny can wash the man's face without using the water in the sink.
- Water You Waiting For?: Penny can water the plant without using the watering can.
- Doggone Thirsty: Penny can spray water directly in the dogs' mouths without moving their tongues.
- Super Mario Bros.: Penny can extinguish Bowser's fireballs using her water cannon.
- Light the Cake: Penny's water can extinguish the candles, requiring the player to move carefully.
- Bamboo Falls: Penny can fill up the deer scare without moving the bamboo.
- Hot Hoops: Penny can extinguish the fire from the rings, rendering them harmless.
- Manneken Pis: Penny can extinguish the fire without using the Manneken Pis.
- Cheeky Beaker: Penny can fill the beaker using her water cannon, albeit at a slower pace than using the items.
- Flammable Goods: Penny can extinguish the fire using her water cannon.
