Twisted Tisha

Tisha is the cleaner of the roster. She sweeps the floors and stays in each area for 10 seconds at a time, and the wiki notes two side effects: sweeping in Ichor puddles makes them bigger, and she can wipe away both Brusha's paint and Twisted Brusha's graffiti from Machines. So she can quietly undo one Twisted's work while worsening another hazard, which makes a floor that has several of these Twisteds hard to read.

Her chase is unremarkable: walk 10, chase 18 (tied for 15th of 37, the median), vision of 26 in a circle and 60 direct, hearing of 125 and attention span of 1.5 seconds. The danger of Tisha is predictability. Since she parks for 10 seconds at a time, you can time your movements around her: wait for her to commit to an area, then pass through the area behind her. Avoid growing Ichor puddles in her patrol, as they are larger than usual. Tisha's own Toon has 4 stars of Movement Speed and Skill Check, and its Tidy Up pulse gives nearby Toons 25% more speed for 5 seconds.

Tisha is a Common Twisted. At 100% Research you receive the Feather Duster trinket, which restores 20 Stamina when you pick up an item, though not capsules or tapes.
