Sonic Mania - Missing Sonic 1 Enemies

Finally made some more Sonic Mania styled stuff. This time, it's every enemy from Sonic the Hedgehog (Sonic 1) that didn't appear in Sonic Mania. well i guess the burrobot appeared during the fight with big squeeze but just shup up hmph
Yes, I know that Orbinaut isn't animated, but that would have been extremely time consuming and tiring; which is why the Caterkiller, who needed to move up and down so his jaw could open without hitting the floor, is so poorly animated with his usually smoothly animated body. Speaking of the Caterkiller: I'll admit, his head here is reused from the Rattlekiller, but the rest of the body was re-shaded by me. And Spike would have needed 5 frames of animation if I were to animate him, and, as you'll see with Bomb, that wouldn't have properly fit on this deviation with the rest, who use 3-4 frames of animation, without alot of frames and loops.
The Bomb you're seeing here isn't the full extent of the animation I made for him, and you can read just a bit more on why that is on the full gif itself, which I will be posting as a seperate deviation here: fav.me/dbzvzvn

Please give credit to me if any sprites from this deviation are used in anything.
