FOUND LOST PEN

 This morning when entering class, Na discovered that her pink ballpoint pen with a rabbit on it had disappeared from her desk!

Na called her close friends: Binh, Ti and Linh. They all decided to form the "First Grade Detective Team" to investigate.

The detectives found small cookie crumbs stretching from Na's table to the corner of the room - the first clue!

At the end of the cookie trail is the small cage of... the classroom hamster named Fatty. Fatty is gnawing on a pink pen cap!

The group gently opened the cage, retrieved the rest of the pen, and patted Fatty who was nibbling deliciously.

Na laughed happily: "Not everyone is the culprit. Sometimes the culprit is just... a greedy hamster!"
