Set right after "Sins of the Grandfather"; crossover with the "My Little Heroines" series AND the "Different Species, Same Friendship" universe. The Discords of Equestria Prime AND the "Different Species, Same Friendship" universe both decide, at the same time, to take their universes' Smoozes dimension-travelling in order to try to be a better friend to them, and end up coming across Beetlejuice, who had a similar idea with the Thing.
