Easter Egg in Save The Adventurers?

Hello all,

I've been playing Save The Adventurers for Android, and enjoyed it a lot, even though the graphics looks kinda old (and some cutscenes are way too long, and you can't skip them for the first time). The genre is somewhat "mixed", it's mostly ADVENTURE, but with RPG/action/strategy elements I believe, so I hope it's allowed to talk about it here. BTW, I'm talking about this one:

So, finally, FINALLY, after 1.5 hours (!), I won the final battle. I don't want to give spoilers here, but if anyone is stuck with the Gnome, I'll gladly offer some hints. I tried the Quiz, and it said there was an Easter Egg in the game. It's in the Underworld map. Anyone has more info on this?

Thanks in advance!
Jaroslav (currently spending his holiday in Slovakia)

p.s.: I've been playing the game on a friend's Nexus 10 (2012)

Hi Jaroslav welcome to Adventure Point   

It's ok to post here but we have What game Are You Playing Now found on page 2 where you can also talk about the game you are playing now. We also have Adventure Game S.O.S. where you can ask for help if you need it.

I haven't played this game but maybe someone else can answer your question about the Easter Egg
