S2·E1 Hole In The Wall

Rudy and Penny visit Rudy's dad's old school from when he was little. Rudy's Dad said he wrote a letter to Mildred about how good she was on reading some kind of poetry. Ever since then, Rudy's Dad 'Chickend out' about giving the letter to Mildred. He hid it under a very rickety board on the floor. Rudy and Penny enter from ChalkZone into the school, to try and not tresspass. When Rudy and Penny get caught, Vinnie, the brother to the construction worker, steps into the old school and finds out about the portal to ChalkZone. Now Vinnie wants to turn ChalkZone into an Ammusement Park!
