That Sinking Feeling - S3.E14

Reggie steals Rudy's last piece of magic chalk and stomps it into the ground. This causes a small portal of Chalkzone to appear in the ground. Reggie's foot gets stuck in the hole he made. Snap realizes this is Reggie's foot and wants to get revenge for what Reggie tried to do to him when he was in Plainsville. Rudy tries to get Snap to leave Reggie's foot alone. But because he has no more magic chalk, he must try to erase a message into Chalkzone to Snap before the Chalkzone is discovered.
