Spiromania

Spiromania was a disease from an Undefined Multiverse, one that was known to affect Human children by replacing their eyes with spirograph designs.
The Kenner toy company sold Spirographs and Super Spirographs, which allowed for the spread of the disease. Once infected, the children would actively seek out other children to infect them as well.
Linkara feared it greatly.
