Green Worm on a Red Mat

I found this worm crawling on the floor in the morning.  It must have come out of the peas that I put on the counter last night.  My daughter followed it and took some shots.  They weren't clear.  On the door mat it felt the presence of my daughter so near that it curled to pretend dead.

It moved after a while to check if the coast is clear.  Then it continued towards the door.
