“I’m bored”, he said. His folks were out, and there was nothing to do.
The koopel (young koopa? What is the right word for that?), read through his magazines, and found an experiment-sort of thing
“Huh, that sounds cool” he said.
So, he checked the what-you-will-need list. The list was:
Balloons (36 inch, 90cm),
Pump,
And a… Space Hopper/hoppity hop (deflated)?!?
“I only have a Shell Hopper though! Oh, well, it’ll have to do.”
‘First, partially inflate the balloon, then let the air out again.’ The koopel wondered why, but he pressed on anyway.
‘Then, put the Space Hopper/hoppity hop inside the balloon.
‘Finally, inflate the space hopper/hoppity hop, and go bounce!’
“Wow!” he said, after doing all of that, with only a bit of accidental shell dashing, “a shell hopper that looks like a balloon!”
He went for a bounce, and there was that comforting feeling you get on a balloon.
“Hey, it hasn’t popped yet!” he said after five minutes “That’s why this is cool! It’s a very strong balloon now!”

This is an idea i've had for a while.
Also, I am aware I previously uploaded this, but this time I made it so you didn’t have to download it.
