Storybook Planets each have their unique place in each game, so giving coordinates is useless.
"This planet really sticks to you."
There are tentacles planets of following types:
- Grayish-black tentacle-shaped rock formations cover the planet. Several suction-cup-shaped terrain features exist as well.
- Chocolate spirals everywhere. On the top of a spiral, there is smoke which should be its tentacle. It is almost exactly like Cattor in terms of geography.
