The Octopi are pair of cephalopods. They live on the beach and like to make music to rhythm of the wind.
When Steve noticed the wind the octopi appeared onto the shore. The first octopus calling him twice. When he noticed them, the first octopus asked him which one of them is dancing to the rhythm of the wind. As he did, both octopi danced differently: the 1st octopus is bending his tentacles up and down while the 2nd octopus is moving it's tentacles slowly and gracefully.
Both octopi have purple bodies, and 8 tentacles with lavender suckers.
The Octopi only appeared in "What Isn't It Time for Blue?".
