Story about meeting a sneaky monkey while stealing eggs

Today, I lost two Secret and Eternal eggs because of someone wearing that monkey skin... I was playing the game comfortably because I was rank 1 on the server. A Secret egg appeared nearby, and I struggled to get it. Just as I was about to bring it back, someone wearing a monkey skin saw me get hit right in front of the safe zone and snatched the egg. I let it slide the first time. It happened to me once too. But when I brought back an Eternal egg, they stole it the same way. That's when I lost it and said, "(Not even polite) Hey, monkey. I worked hard to get this, why'd you steal it??" And the monkey said, "Sry, it looked too tasty...." What's with the "...."? Who's gonna let that slide? If you see someone with a yellow trail, wearing a monkey skin, and doing the same thing as before, please tell me their ID right away. (Not that I'm gonna do anything, just wanna get 'em back... ^^)
