Looks like you've stumbled across something hidden!  A secret!  A clue!  Welcome to the quest within a quest!  Are you interested?  I have a "friend" who needs some help.  Will you be the one?  If so, send a picture of me via email to the one who calls himself QuestMaster. 

Doing so will unlock a series of hidden quests that will be very rare, indeed.  They will involve rather... unconventional learning opportunities.

You'll be among the few to be called on this special mission!  Finding these hidden quests is like belonging a super-secret, ultra-rare, uber-nerdy, elite club, so don't let others know how you got here!   Complete all the quests and you'll earn the Golden Rocket Achievement!
