Don't let dog drop it!
Color: Angry Octopus
Was great for a minute. My dog dropped it from mouth onto linoleum floor and ... now it won't do anything but beep once. So, waste of money.

Keeps my dog entertained
Color: Blue Octopus
Cute! Kind of annoying but my dog loves it and it keeps her from tearing the house up. It’s probably my dog more than the toy, she tore the Velcro off within a week. I sewed it back up, but she destroyed that too. I wish they had just the octopus plushie I could buy to replace without getting a second motor.

Works as expected…but scared the “stuffing” out of my girl.
Color: Angry Octopus
It’s cute and works as described. Can’t use it because my dog is TERRIFIED of it. 😂
