Ringo was working on Bot.
"Let's play Space Pong!" Lucy said.
Ringo shook his head. "I can't.
Bot broke down again.
I need to fix her."
"You need a new robot," Lucy said.
"Bot is old and clunky."
"Bot is the best," Ringo said.
"I can fix her!"
Lucy went away.
Ringo looked inside Bot.
Her parts all looked fine.
Bot's wires looked fine too.
"Hmm," Ringo said.
He shined a light inside Bot.
Then he saw something.
"Aha!" Ringo took out a rusty part.
"Bot just needs a new hex link.
I knew I could fix her!"
Ringo went to the supply room.
He asked a worker for a hex link.
The worker laughed. "Why?
New robots don't have hex links!"
Ringo grinned. "My robot is old."
The worker looked around the room.
He didn't see any hex links.
He looked them up on a computer.
"Bad news," the worker said.
"They stopped making hex links."
Ringo gulped. "How will I fix Bot?"
