I switched Caillou and Fievel's voice because Ivy does work better on Fievel. Anyways, he gets rewarded by his sister Tanya for grounding Caillou.
Fievel: Caillou, you are grounded grounded grounded grounded for 100000000000000 years! Go to your room now!
(Caillou enters angry)
Fievel: Yes, I grounded Caillou.
Caillou: There he is. Fievel Mousekewitz grounded me.
Boris: And you deserve it! You are grounded until your dying day! Go to your room now!
Boris: Thank you for grounding my son. Go home now.
Tanya: Fievel Mousekewitz, you are ungrounded for grounding Caillou. I see you changed your voice.
Fievel: That's because I really hate it when my voice is Shy Girl so from now on, my voice will always be Ivy.
