Set #674 included a black pinto Arabian and dark palomino Andalusian foal. In the 2003 and 2004 catalogs, the #674 set is called 'Foals - Black Pinto and Dark Palomino'; however, the boxes from set #720101 were advertised as 'Dark Palomino and Black Pinto Foals'. Late in 2005, set #720101 was released through Target and similar stores (and not pictured in the catalogs). This set included a black pinto Mesteño and either a dark palomino Andalusian or Morgan foal.
Set #674, and specifically #3055FO, were on the Retired List for 2004, so then the dark palomino Andalusian foal was packaged with the black pinto Mesteño foal in set #720101. The black pinto Arabian foal was never released with the dark palomino Morgan foal.
