Strober can be found in The Docks B . Their color changes from red, pale pink, back to red, and then purple. They give Madotsuki the Fat Effect when interacted with.
- When the Cat Effect is used, their color changing speed will double. Strober is not mobile, and will not move towards Madotsuki.
- When stabbed, the speed of their constantly changing colors decreases to a third of the original speed before they die.
- In Yume 2kki, the character "Flashing Trombonist" highly resembles Strober (even going as far as to strobe like Strober).
