This is Tube! While not their official name, that's what their creator, Rachel, has decided to call them! Squishable has decided to sell it as a caterpillar because "Squishable Tube with Face" doesn't quite have the same ring to it, we hope you understand! Dimensions: 6"(w) x 12"(d) x 6"(h). Made of polyester fiber. Suitable for all ages!
