KONG® Holiday Knots Belly Hippo gives Santa’s bowl full of jelly competition! Soft and cuddly on the outside, a strong, durable rope ball on the inside makes its belly round and weighty. This dense internal skeleton rope ball adds heft and movement that entices instinctual thrashing, flinging, and light chewing. A squeaker in this hippo’s head piques dogs’ interest and adds excitement to play sessions. Knots Belly Hippo is also ideal for dogs who like to carry their toys, as well as for naptime snuggles.
