Seas and oceans occupy significant areas on the planet and humanity has long been used to discharge garbage. This bothers scientists and they decided to fight pollution. First you need to convince those who clog ponds to stop this, and then you need to start cleaning the seas and oceans from already existing garbage. For this, a special underwater drone was invented and designed. You will manage it at the Someting Below The Sea, collecting a variety of garbage. The drone is not at all invulnerable. Some underwater inhabitants pose a threat to him and, in particular, jellyfish. Faced with them, the drone loses energy in the SventHing Below The Sea.
