There are three characters in this film: pink octopus, orange octopus, and a truck driver. I guess the pink octopus and the orange octopus are in love. The truck driver seems to be a tempered person, and is under an absession of getting the octopuses.
I think the truck driver wants to deliver the pink octopus to a restaurant, and the orange octopus wants to help the pink octopus out.
The conflict in this film is that the driver bought the pink one from a shop and the orange one trys to get her back. Neither of the driver nor the orange octopus give up.
In the end, I think the pink octopus reached at the back of the bird and start to attack him. Then, the bird releases both of them. However, where they landed was a dog's head! Though it seems like they will start fighting in a moment, the dog smiles nicely and took octopuses to the sea :)
