See-Inside Cars: Sodor Horse Show gives the ability for the player to look through two cattle trucks painted in blue.
The first one includes horses being breeded with their owners whilst the second contains horse related farm items.
The pack seems to relate to several TV Series episodes such as Harold and the Flying Horse and Wonky Whistle.
See-Inside Cars: Sodor Horse Show from TrackMaster arrives in stores worldwide soon.
Thanks to SteamTeam for the alert.
