Watermelon Seeds?

I haven't tasted butong pakwan for a long time (years na!) and upon seeing it being sold in a pasalubong store in Bulacan, I bought a small supot (P35). Of course na-excite si Isabel since fave nya ang watermelon. She find it also easy to crack open the seeds.

But thinking out loud, is it really watermelon seeds? Looks suspiciously different to me if you compare the seeds of a 'real' watermelon and the butong pakwan being sold. So what kind of a seed is it?
