Zipcaster

The Zipcaster is an upcoming special weapon in.

Description
The Zipcaster transforms the user into a form with long, stretchy arms. While in this form, the user is able to grab onto far off walls and travel quickly to the targeted spot, creating a small explosion upon arrival. When the ink runs out, the user will travel back where the special was activated, ending the special. The appearance of this form changes depending on the player's species and ink.

It appears to be part of the Splash-o-matic's set.
