Cakeday incoming! Easy puzzle for Shadow of Mordor GOTY [lvl3+]

Ahoy, fellow pi-rates. My cakeday is incoming, by the end of the month I will be on this site for 4 years. Time flies.

To celebrate I'll be giving away a copy of Middle-earth: Shadow of Mordor Game of the Year Edition, and all you have to do is solve this relatively easy cake-based puzzle: http://www.itstoohard.com/puzzle/xbqGTNwi

The giveaway is for lvl 3 and up, which I assume most of you will have by now. As always, it's a private giveaway, so please don't share the link. It ends March 30th, on my cakeday.

I reckon jigsaw will take you the longest, so try answering the questions while you slice that pie.
I'd also suggest not trying to solve the jigsaw on an empty stomach.

Have fun, good luck and... I'll be providing hints if it proves to be too difficult after all.
