"'Cause It's Make Believe" is a song from The New Adventures of Winnie the Pooh pilot episode, "Pooh Oughta Be in Pictures", sung by Christopher Robin, Piglet, Tigger, and Pooh. The song was sung during the end of the movie theater scene, much to the usher's dismay.
Lyrics
Tigger: Well I once saw a monster pillage
A house, a block, an entire village!
He ate until he reached his fillage
But me? I stood right there!
I've seen 'em ninety stories high!
Seen ones that swim and some that fly!
But I never flinched when they stomped by
'Cause Tiggers don't get scared!
Tigger, Pooh and Christopher Robin: So you'll be alright, 'cause it's make-believe!
Tigger: It's just a light that shines real bright and bounces off a screen.
Tigger, Pooh and Christopher Robin: So you'll be alright, and quite safe too!
Tigger: There's no need to be scared when a Tigger is there with you!
Piglet (spoken): But what about the usher?
Pooh (spoken): Oh, don't worry, Piglet, he's not in the movie.
Tigger: I've seen 'em rip, I've seen 'em tear
I've seen 'em floating through the air!
But I stood by without a care
'Cause Tiggers don't get scared
Christopher Robin: It's just a buncha movie tricks to make you think this thing exists!
Tigger: A piece of film is all it is, there's really nothin' there!
Tigger, Pooh and Christopher Robin: So you'll be alright, 'cause it's make-believe!
Tigger: It's just a light that shines real bright and bounces off a screen.
Tigger, Pooh and Christopher Robin: So you'll be alright, and quite safe too!
Tigger: There's no need to be scared when a Tigger...
Pooh: ...Or Pooh!
Christopher Robin: And don't forget Christopher Robin too!
All: There's nothing to fear when your friends are here with you!
Tigger (spoken): See you in the Hundred Acre Woods! Hoo-hoo-hoo-hoo!
