The fabulous Tongue Twister is ideal for nervous horses or for those in smaller stables as the durable ball attaches securely to the stable wall rather than hanging from the roof. With inserts for two Little Likits you can keep your horse entertained by using different flavors on each side, or even by just using one Likit at a time to make things more challenging! . Challenge Level: Medium/High. Refills not included (uses 2 Little Likit Refills).
