Abyss shark is a bummer

Just bought abyss shark on sale and I’m so bummed, it feels awful: slow, somehow doesn’t seem to actually open its mouth at all, gameplay was all laggy and it somehow couldn’t eat fishes I was literally bumping it into head first (I thought the game itself was lagging, quit, played with other sharks—everything was fine. Played abyss again and it sucks. Gosh, I had no idea. Totally regret spending gems on it.
