Mini Whinnies Pintos #300115 from 2006-2007, included the Cantering Morgan, Running Walk TWH, Standing QH, Trotting Morgan, Walking Arabian and the Pulling Draft. Released later in 2006, so not pictured in the catalog. This same set was released by Target as #720201.
There is a similar, updated version of this model #300181 Surprise Series 2 - Daisy from 20016-2018 (see separate record). There are slight differences in color and pattern, the hooves on the updated model are a bit darker, and the white areas are colored plastic compared to the painted white areas of the Pintos sets.
