Remember on one of the spoilers that on the third movie of How to Train Your Dragon that Hiccup will be reflecting of the past when he was still a boy. So in this scenario, Hiccup will be older and possibly telling children about his story or something...

Okay back to my point. All of us might be wondering what Hiccup and Astrid's kids will look like, right?
So you see, in How to Train Your Dragon's official page on facebook(or maybe on other sites as well, I don't know), they posted this...

So did you look at the picture closely? Some of you may already seen this pic already......
Okay, notice the two little kids on the paper airplanes? Look at them closely...

The boy on the top, on the night fury paper airplane (I would not say that the night fury is Toothless because Toothless has a missing tailfin, the night fury on the picture doesn't have a missing tailfin) has blonde hair just like Astrid. Has messy hair like Hiccup.  Is possibly wearing Hiccup's helmet. Wears shoulder guards like Astrid. And the boy is wearing a shirt like Astrid's.

And the girl on the bottom,  that is on the deadly nadder paper airplane has strawberry blonde hair which is a combination of Hiccup's auburn hair and Astrid's blonde hair. She wears a headband like Astrid. Wears green clothes just like Hiccup (How to Train Your Dragon, How to Train Your Dragon 2, the tunic underneath his armor, Riders of Berk series, and Defenders of Berk series).

So what do you think? Could this possibly be a clue on to what Hiccup and Astrid's kids look like?

Tell me your opinions. Just no harsh, rude words. No cursing and swearing please.
