One day Zoey was outside in the backyard playing fetch with Milo, her amazing, talking dog.

Suddenly Zoey got a call from the zoo’s security guard saying he needed help!

Zoey and Milo got onto their super scooter and zoomed quickly to the zoo across the street.

Once they got to the zoo, they noticed all the animals were missing! Zoey got her magnifying glass out and tried to find clues.

Milo started to sniff for evidence. He checked behind the cages and under the trees, but Zoey was the first to find a clue!

"Look! There are cracker crumbs," Zoey said. 

"Hmm... who likes to eat crackers?" Milo said.

"Dr.Hammy loves to eat crackers. He must have taken the animals!" Zoey said.

"I see there is a trail of crumbs. We should follow the trail and see where it leads," Milo said.

They both discovered the trail stopped in front of a lab door!

As they opened the door, they discovered all the missing animals, safe and sound!
