In Spelunky 2, when you encounter the jungle stage (2-1) you seem to be able to start finding one of three siblings (triplets?) in 3 separate caves. After rescuing them, they just thank you and you can walk away.
After saving them, I thought they would be playable characters, so I didn't think much of it, however, after searching around the initial floor/starting area, I noticed that they're nowhere to be found.
My intuition, then, is that if you rescue all three in one run, they give you something, similar to Yang (The turkey NPC who rewards you when you gather all three turkeys)
Can anyone confirm that there is a reward, and if so, what? I can never seem to find all three in the same run, and there is minimal information about them online, so far.
