There's a great big bus way up in the sky
And everyone said it would never never fly
With a poop poop chugga chugga bing a bang bing
This is a song that we always sing
Boom boom chugga chugga boom boom chugga chugga
Boom boom chugga chugga boom boom
Boom boom chugga chugga boom boom chugga chugga
Boom boom chugga chugga chug boom boom
Think about hanging on walibis and snakes
Open the steam bow let go the brakes
Chuggie chuggie claddie claddie chug chug chug
Off we go with our funny old bus
Boom boom chugga chugga boom boom chugga chugga
Boom boom chugga chugga boom boom
Boom boom chugga chugga boom boom chugga chugga
Boom boom chugga chugga chug boom boom
Over the hill and over the dale
We're on a big quest that must not fail
We're finding a way to make the air clean
It's all to do with very hot steam
Boom boom chugga chugga boom boom chugga chugga
Boom boom chugga chugga boom boom
Boom boom chugga chugga boom boom chugga chugga
Boom boom chugga chugga chug boom boom
Boom boom chugga chugga chug boom boom
