i.e. the opposite of Teenage Mutant Ninja Turtles
After years of not fighting crime, four octogenarians living in a retirement village stay exactly the same as they have always been. Except now they all take part in a group art therapy session three days a week.
The art therapy facilitator, Tweezer, gives them all turtle themed nicknames: Shelly, Slow'n'steady, Galapagos, and Mitch McConnell. Shelly's grandson, October von Diamond, often blogs about their adventures in watercolour to the interest of no one.
Their arch nemesis, Taper-upper, often rummages through their discarded artwork, only to tape them together and display them on the community message board--much to the chagrin of the OIPP.
