Help with finding strange balls?

I had this ball that was blue, looked like it had teeth, and opened in a similar way as a pokeball. It held either a blue whale with a horn, a red dino with shades and black claws, or a weird green monster that looked similar to the dino, but without shades. I’ve tried google and I can’t find it. Someone please help me find out what it was called. I think the ball also had eyes.

Only thing that comes to mind is a “kinder-surprise”. Now these were cool although I never got into them.
