Jimmy the jumping jackrabbit just got a jumbo jar. He jumped with joy all the way to Jill's jungle gym.

"Jill!" Jimmy called out. "Join me for a juice party!"

Jill the giraffe poked her long neck out from behind a jeep.

"Jimmy! What's that big jar for?"

"I'm making jam today," Jimmy said. "I need to pick jelly beans and juicy berries."

Jill and Jimmy jogged to the magic garden. The garden had giant jelly beans growing from the ground!

"Wow!" said Jill. "These are huge!"

Jimmy's job was to pick the jelly beans. Jill's job was to mash them in the jar.

"Be gentle with the jar," Jimmy said. "It might break."

Just as Jimmy jumped to get a purple jelly bean, Jack the jaguar came out of the bushes!

"Hey! Can I join your jam making?" asked Jack.

"Sure!" said Jimmy. "Just don't juggle the jelly beans."

But Jack couldn't help it. He began to juggle five jelly beans at once! Up and down they went!

"Jack! No!" Jimmy yelled.

Too late! Jack tossed a bean too high. It came down with a BOING on the jar!

The jar didn't break, but it jumped up like it had springs! It bounced all around the garden, making everyone laugh.

"A jumping jar!" giggled Jill.

They chased the jar all day long. When they finally caught it, they made the jumpiest, bumpiest jam ever. It made everyone who ate it want to jump and dance!

"Best jam in the jungle!" they all agreed as they jumped for joy.
