Description
Trélazine, the famous witch of the Ecomuseum, is back! She had invited her friends to the Ecomuseum to celebrate Halloween. But during the party, an object went missing!
Quickly singled out as the prime suspect, the Ecomuseum’s famous witch is counting on the families’ sharp minds to uncover the truth and prove her innocence.
Inspired by the game Cluedo, this activity will allow participants to use the process of elimination to solve a series of puzzles and mini-games. As they investigate the park and the museum, the children will have to figure out which tool was stolen, who the culprit is, and where the theft took place. The adventure ends with the search for a 3-digit code to open a safe and verify the answers.
Every child who helps Trélazine will go home with a tasty treat!
