Reinforced Articulated Shark

The original Articulated Shark was a little to wibbly wobbly in the up down articulation for my little nephew to play with. I added some additional parts to stiffen the shark out quite a bit. It is still just as wibbly wobbly going side to side. The mouth still opens. The connections I added aren't the smoothest cause I've never remixed before. So if anyone wants to smooth them out, that'd be awesome. I recommend epoxying or super gluing the tail fin in place because it is a very loose joint and pops out easily. Edit - 1/9/22 - Made some updates that should help with printing the upper teeth.
