Homnibus' Imaginarium

The Imaginarium is a special room hidden in Homnibus' hovel that appears in the Smurfs cartoon show. It consists of a chair and several special crystals that magnify one's imagination and allows that person to share his imagination with others in the room. In the cartoon show episode "Papa's Day Off", Homnibus allowed Papa Smurf to use the Imaginarium to see what his little Smurfs would do in an emergency situation if he wasn't there to take care of it.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf stories, Homnibus' Imaginarium inspired Papa Smurf to create one for the Smurf Village, only its version allowed its users to create realistic environments that they could interact with. Empath has used Homnibus' Imaginarium during his visits with the elderly human wizard and finds it interesting, even if he could nothing in it but sit and share whatever it is he could imagine with Homnibus.
