Bud waves goodbye as he and Bun begin the long journey back to their home planet. Will they ever have another opportunity to visit Earth?

Bud and Bun have never ridden a train before...

Oh! Bud's friend Bun is also on Earth? What a surprise!
#BudonEarth

I hope you looked both ways, Bud...

Will Bud make it to the top?
