There are two modes: light mode and squishy mode.
 
★Light Mode
Squish it and the light comes on!
In Light Mode,
you can change the light intensity in three stages each time you squish Mimikyu! It will light up for 30 minutes continuously. It glows softly when you turn it on. → Continue squishing it to make it brighter. → Squeeze it even more and it will slowly get brighter or dimmer!

★Squish Mode
Squish Mimikyu and it will light up. Let go and it will go out.
Each time you squish it, it will change to one of four brightness levels!
If you don't squish it for a while, it will blink, begging for more squishing! Try squishing it slowly, squishing it a little faster, or try out different light effects.

Batteries: Requires two AAA alkaline batteries (batteries sold separately).
