Summer holidays are just around the corner, and the children from the Apple Valley are heading to Bad Wilbek to perform their successful play once more. Without further ado, Grandma Astrid loads all the ponies onto the tractor “Brummhilde“, because naturally they must also all attend! Leading the way is the little pony inspector Carrot, who quickly smells his next case when utterly strange events start happening in the small town's spa park. Not only does someone appear to search for something there at night, the town also seems to have a thief on the loose! It's obvious that Inspector Carrot and the Apple Valley detectives must get to the bottom of this - but the case seems to be trickier than expected. Hopefully Carrot's detective instinct won't fail him in this thrilling adventure...
