A Myth ?

The Rainbow tipped Butterfly is he really in the game? I have nearly 300 hours of game and I have never seen him! Like hello are you real... I know where to look and when but he just never appeared! Is he a glitch or something

EDIT: YOU ALL!!!!!!! I HAVE CAUGHT ONE!!!!!!!!!! 🥳 THANK YOU ALL FOR YOUR ADVICE AND HOPES !!!!! Love youuu ❤️
