The area surrounding the shark is too big. Is it possible to adjust the height of the collider area? I tried putting in numbers in the parameters after the rectangle/circle box but it didn’t work.

Have you tried editing the shark animation itself? The bottom tool on the right toolbar should resize the animation canvas to fit the actual size of the shark and then the collider area will naturally be a normal size.

I just tried it and it worked for me, but if you run into any problems, respond and we can look further at it
