Who is Max Mouse? (2) - S2.E18

Max Mouse continues to wreak havoc in Hurston. Jamal Lenni, and a lot of other kids grades get changed, false alarms go off and a child is nearly killed in a fire because the fire department is responding to a false alarm. Ms. Kelly has had enough. The kids have never seen her so upset. Then there's a new message on the computer but this one looks serious. The team's three suspects are Calvin, Erica and Janice.
