In the third part of the Symbiosis saga „Core“, the protagonist comes to a halt for a brief moment in her search for „the solution to the game“ and devotes herself entirely to a symbiosis that takes on the role of a source of energy in the dramaturgy of the game. The protagonist explores the coexistence of an octopus and a mangrove tree from multiple perspectives.

The tentacles entwining the tree seem to feed on the branches of the tree living in the water. A reddish liquid (is it blood?) drips from warts on the surface of the tentacles, like an absurd fountain. While most of this liquid just disappears into the vastness of the ocean, a few drops find another purpose. Passing shell-shaped vessels hope for the right moment to be fertilised by a drop and thus find the purpose of their existence.

„Core“ is filmed in a mangrove forest in Southern Mozambique.
