see a sincerity in a green cave

guys, my friend which is my best friend. he told me that 1 week ago he saw an epic on a green cave. and told me it was sincerity. he is quite new around 2-3weeks playing this game, so he didnt tell me that he saw a sincerity until 1week after he saw it. cause he doesn't know that sincerity cant be obtained that easily, he also didnt remember the exact place

so the story is:

yesterday we were chatting about angelo, and he was complaining he hadnt seen angelo until now. he told me that he saw only a mimic "which is tresha" on a normal map. and after that i told him that tresha can be founded in a green cave, and we were speaking about green cave and suddenly he told me that he saw a sincerity in a green cave 1 week ago. i was told him that purity cant be caught in a map but he was pretty sure about it,,

so i wonder a green cave can give a free sincerity? that would be nice

his progress now is
expert : until canon -1
veteran : until sealed space -12

not sure about his progress 1 week ago. so i wonder, if a green cave has a small chance to reveal a sincerity / it is in the map where u cant use dice to land on a green cave. @@ im sure he wasnt tell a lie unless he saw it wrongly, but im sure he wont forget it because its still 1 week although he forget the location

in my mind i thought,
maybe is it in the volcano 8 expert? or all green caves have a chance to reveal sincerity?

i tried to ask support and they havent reply me yet.

As far as I know, Green caves only contain Tresha and Cheeky, and Purple Caves hold various Epics.
Perhaps he has mistaken a Mini Boss / Boss Tile for a cave?

I'm pretty sure he's mistaken as Koenaj said maybe it was a mini boss

he tried to catch it but failed. he only has around 10 cards or something. ya he didnt catch it so there's no proof. actually i dont believe it 100% as well. but i gave him the picture of phony, i gave him flicker picture and the evolution as well, he told me that he was sure it was a pinky horse.

now he made me curious about what is inside volcano expert 6 and 8. the green cave one. because in denira spreadsheet there was no data about it. anyway i asked support already and im waiting for the answer now. if sincerity can be caught in a green cave than everyone can have a pressure monster. it will ruin pvp !! =,= maybe theres 0.00001% for sincerity to show up in a green cave? but i'm sure if its not an error from haypi than he just the luckiest man in the haypi world that saw the first and maybe the last sincerity in a green cave although he didnt catch it.

CHEEKY IN GREEN CAVE!!!
I never saw it

Does he remember around what levels he saw it ? at least where if norm/vet / exp or at least what map maybe i can try myself to search for it

nah he doesnt remember thats why i mocked him that day. btw can someone try to ask to support? i asked it and get no response. 2 / 3days already. just ask whether sincerity can be found inside green cave

eennngggkkk! False Alarm!
Impossible

Asked support... Here's their response. ^_^

Aaaaaaaaaaaand it's solved
