When entering the museum, we provide guests with a leaflet.
If you look closely at the precautions on the back....

Among them are some notices unique to the museum
like this one.

It says, "'Mice' are not allowed in the museum" they say (laugh)!
I'm sure you can guess why now.
"Some guests start laughing just from reading this part of the leaflet♪"

It's also clearly displayed on the panel showing the museum map at the reception...

Actually, there is a "mouse" that has secretly sneaked into a certain spot in the museum.
Where exactly it is and how many are hiding is a secret.
Because Doraemon would get scared, you know.

If you happen to find a mouse,
please quietly take a picture without alerting Doraemon.
