The Jungle entity

I was playing Minecraft 1.7.10 With mods such as Pixelmon, Flans, and Ragdoll Corpses. I don’t remember much but all I know is there was this thing in a jungle biome that isn’t featured in Minecraft or the mods. I was playing in creative mode looking for a jungle temple to raid when I turned around to see some strange entity that looked like a player which was impossible because I was in singleplayer, the thing turned around facing directly at me even though I was at least 50 blocks away. Its face was pale just like the rest of its body, on it was face of herobrine, although I don’t believe it was herobrine because it looked pale whereas herobrine is just Steve with white eyes. I was about 7 to 9 when it happened so when I saw it I closed out of Minecraft and didn’t get back on it until I was 11.

I was young so I didn’t even think about taking a picture
