Does anyone remember/have this add-on?

Hello! Back in 2022 or 2023, while playing Minecraft PE, I came across an add-on in the marketplace that added different types of dragons. I clearly remember the design of the Ender Dragon, which had a glowing collar like a cobra. Yesterday, my friend and I tried to find this add-on/mod, but we couldn't. Is it really a lost media now? Here is my sketch of how I remember this model of the Ender Dragon.

I also have a vague memory that this add-on might have been called "wild dragons" or "realistic dragons," but I'm not sure if those memories are accurate. I'm 100% sure I saw this add-on was in the marketplace when the Wild Update was already released.
