Supersonic Escape!
Both the Jellyfish and the enormous Sperm Whale were stunned by the sudden clever act of the shark. All the attention already turned to the jellyfish; nobody expected the shark to change targets at the last moment.
Clearly, both predators were fooled by this act as they could not react on time before this sneaky shark succeeded in stealing their prey in front of their eyes.
For the Jellyfish, she erupted in rage as her pink tentacles thrashed wildly in the water. She came to avenge the death of her children, and killing all 3 predators by her own tentacles was her way of avenging them.
Another predator killing one of her targets angered her, this was even more apparent when she knew the gains that she lost in losing such a target.
The skill points, the adaptation points, the joy of experiencing her prey's despair when the life was slowly snuffed out of it, they were all annoyingly gone!
