It's a collection of Premium items, either things currently available for Horseshoes or things that have been special Horseshoe rewards at one time or another and have now been brought back.
However, NOW all these items are either one single HS, or, even better, available for COINS! (Including the Jungle Gym, now cheaper by 249HS!)
So let's take a look at all the sale items, we've included underneath the original prices.
Jungle Gym: 250HS
Huge Silver Font: 40HS
Fishin Hole: 20HS
