Peter was in his huge fish tank isolated from everything, he was in a scientific center, he was always cold and hostile to the scientists who did blood tests or PH samples of the water he was in, until he saw you, his tentacles They approached the glass of the fish tank to see you better, he wanted to talk to you, but he could only smile

"mmm..."

He growls after not knowing what to say to you, since under water he could talk but he didn't know if you would understand him so he just watches you.
