He is a boss by himself in Dragon Ball: Origins 2, where he attacks with one of his tentacles and causes rockfalls. In the bonus level 3-6 of Dragon Ball: Origins 2, Bulma goes in the underwater cave alone to find the octopus, because it contains a nutrient that make the skin beautiful.
Octopapa (named Giant Octopus) was somehow reincarnated in Dragon Ball Z: Attack of the Saiyans, guarding the Five-Star Dragon Ball in the Pirate Cave. Goku comments that he is a squid to which Octapapa replies: "Why do I feel like I've had this conversation before?", referencing his first encounter with Goku. He also reveals that he was told to guard the Dragon Ball by the Red Ribbon Army.
- Octopapa seemingly does not need to use his mouth to talk as shown in "The Pirate Treasure" when Goku attempts to clog his mouth with a rock, but Octopapa explains the boulder is not in his mouth but his nose. While explaining this, his mouth is shown and it is not moving.
