- Charybdis's and coelanths can eat other creatures.

- Split charybdis's tail into several parts, the single stiff tail limb made it too difficult for it to turn around.
- Option to override the torque that's used to rotate the mainlimb of swimming creatures to the correct direction.
- The scale of the characters' limbs is taken into account in EditCharacterScreen.
