Each dinosaur can be squeezed and stretched! The dinosaurs are slightly weighted and they have little styrofoam balls in the head and tummy that add to the sensory experience. The little balls make a quiet crunch like sound when they are squeezed. Dinosaurs unstretched are about 3"-4" long and 1.5"-2" wide. For example, the triceratops is 3.5" x 1.75.
