"It's Gonna Be a Beautiful Day" is a song sung by Baby Lamb at the beginning of the Season 5 episode, "Life of a LEGO". 


Oh, a beautiful day in a beautiful world

Chasin' all the clouds away

Life is a dream when you know you can sing.

It's gonna be a beautiful day

It's gonna be a beautiful---


  • The song was originally from an animated Looney Tunes that was a pitch pilot to a canned Looney Tunes series called "Laff Riot", which would eventually become The Looney Tunes Show. It was sung by Bugs Bunny (voiced by the late Joe Alaskey).
