IMPenetrable, which is sponsored by Lincs Archiving, will be at the shopping centre until June 6, 2021.
The artist, Mik Richardson, has painted several Mickey Mouse characters into the design. See how many you can spot and pick up an entry form from the shopping centre before putting it into the red postbox next to Impenetrable.
Entries will be put into a prize draw to win a goodie bag.
