The Spirit Family Play Set with Rain #5312 was originally released with the Morgan Mare in 2005. The Paso Fino replaced the Morgan Mare for 2006-2007 (maybe late 2005 as an early box still has a copyright date of 2005 and included a 2005 catalog). Set included a doll, wolf, eagle, hitching post, camp fire and tipi.
Side note: This set pictured came with a 2004 box catalog, so this set may have been released late in 2004, or early in 2005 with leftover 2004 catalogs.
