Germany:

Rainbow Ponies

There were six characters in the 'German' release of the Rainbow Ponies. From Mondschein and Hümmelchen - who looked enough like the mainstream characters to be recogniseable to all - to Regentropfen and Nachtlicht, two entirely new personas.

Please note that the links for Mondschein and Hümmelchen lead to the Moonstone and Flutterbye pages, since they are easily inter-confused.

The set consisted of one unicorn, two pegasi and three earth ponies. As far as I can ascertain, these were issued some time around 1987 as "Regenbogen-Ponys" in German speaking countries.
