Holly thought of some super yellow hat ideas such as he could do juggling on New Zealand's got Talent and he could train for Wipeout! Her black hat thinking was that he doesn't want to be a dog and his tentacles could get dry and stop sticking if he wasn't in water.
Max though of black hat ideas that an octopus shouldn't have a collar and he does not want to be a puppy!
Have a look at the Octopus writing. What do you think would be good about being an Octopus?
