Nick Jr. ID - Mice (2003)
Logo: In a mouse house, some cheese and a little blue mouse are seen. Then an orange mouse appears, and they both lay the cheese down and eat it. The words "NICK" and "JR." fade in on them and the orange mouse hiccups.
Variant: A short version exists, starting with the mice eating the cheese. The logo fades in and the orange mouse hiccups, then it zooms to the bottom right corner and fades to a "Nick Jr. Play Along" interstitial.
FX/SFX: 2D animation.
Music/Sounds: A 5-note theme with a "SQUEAK" sound at the end. Sometimes, a female announcer says "Don’t roll away, there's more ahead, on Nick Jr.!"
Scare Factor: None to minimal.
