The squirter bears a syringe-like appearance, because it is from Jenny's doctor toy set. It features Sunshine's face, with a changing expression depending on the state of the squirter. It can hold a variety of liquids that can be sucked up for later when standing on a puddle.
The squirter is first seen in the office where Dr. Duke Harold is working in. Unlike Plug Into Adventure, it features Chibi-Robo's logo in place of Sunshine's face. It's used heavily in this game as a means to grow flowers from a bud state into a full bloom. The player controls it with the touch screen.
The squirter returns in this game, similar to the previous games.
