(Tillie pulls the birthday train up the mountain with Alvin and Brittany sitting on Tillie's cap roof, Johnny 5 in the 2nd car with Rollo and Jeepers, Simon and Jeanette sitting on the roof of the 3rd car with the giraffes, Theodore and Eleanor sitting on the roof of the 4th car where the Three Stoogebots are inside with Stretch, Missy, and Handy Pandy)
Tillie: I think I can, I think I can, I think I can, I think I can...
Rollo: When your feet are on the ground, stand up and face (stands up but gets blown back in the face by smoke, which makes Jeepers, Simon and Jeanette laugh) whatever your afraid of. When pandemonium is all around...
Missy: That's when you find out what it is you're made of.
Rollo: (while pulling out some flowers from his hat) If you will just believe it's true. (Chip flies at the flowers, picks one, and takes it to Tillie) Then there is nothing you can't do. There's not a mountain that you can't climb. There's not a river you can't make it over There's no tomorrow that you can't find if you try I know you're gonna make it. Nothing can stop you now!
Tillie: I think I can, I think I can, I think I can, I think I can, I think I can, I think I can, I think I can, I think I can!
Entire cast including the The Chipmunks and Chipettes: There's not a mountain that we can't climb! There's not a river we can't make it over! There's not tomorrow that we can't find if we try! You know we're gonna make it! Nothing can stop us now!
(instrumental)
Entire cast: Nothing can stop us now! Nothing can stop us now! Nothing can stop us now! Nothing can stop us now...
