well, in Chimdi Origins, Mimi is shown with a pencil which if i remember correctly could draw things like cover to protect him/her/can’t remember.
basically he/her/whatever could use it to summon a bridge, gun, lever, ladder, lift, etc in order to be a super versatile character.
the Tablet and Pen on the other hand would make him/her/ravioli way faster, draw things quicker, move them around using the pen and being able to instantly fill in gaps like a broken wall or doorway.
however, it is limited by a 4 bar battery that floats over their head which drains over time but can be extended by connecting (somehow) to power source or just not using the mode as often.
