These cute capybara pet stress toys are so fun to manipulate. The animals are filled with a fine granular almost sand-like filling surrounded by a soft and stretchy silicone shell. The critter is super soft and slightly weighted and has a sand filling inside that add to the sensory experience. The little balls make a quiet crunch like sound when they are squeezed. This makes the capybara irresistible since you can squeeze, poke, pull, stretch and bend it! Smash it flat and bring it back to its original shape. Each critter can be squeezed and stretched! This soft large rodent is 3.5" tall x 2.5" wide x 2.25" thick when unstretched. (it can easily stretch up to 6").
