Arthur's Missing Pal/Transcript

Arthur: Count me out.

ARTHUR: Pal!

D.W.: All right you caught me, I confess. I did it. But it's not you think.

Flashback D.W.: Toilet Water!

D.W.: I did. Then I open the door and Pal went outside. I am sorry, but I think he really really had to go.

Arthur: You're right. He really did.

D.W.: Arthur, don't you hear me? Arthur! [Screams] Arthur, get him out of my sandbox. Now!
