Make like Zelda and use Link to your advantage [Now with Answers!]

EDIT!

All gone now. Thanks for participating guys. :) I shall provide answers below and, well, 2/3 ain't bad in terms of people who did actually let me know they were taken. Thank you to you and I hope good fortune finds you in this dreadful trundle through an all too brief sneeze of time we call life.

To the person who took the humble gift link without saying thanks, I suggest you fess up or something may happen. I had one thought which was to make the silent, ungrateful ninjas stub their toe on the castor from a divan bed. You know the ones, where it makes you feel like you're ripping your leg off even though you just hit your toe a bit. Then it would get infected and fall off, and OH NOES! it was your big toe and now you can't balance properly and walk like a proper bell-end. So, you really do want to say thank you when you ninja shit, guys!

Answers: The number was 7, the answer was obviously 42. Apologies, I cocked up this one a bit, so sorry if you got them right and didn't get it. I accept full responsibility and will stub my toe on the castor of my divan bed at some point, to atone.

Answers: The Cretaceous-Tertiary boundary extinction event, usually abbreviated to KT, was the series of events surrounding the extinction of the dinosaurs. While the famous meteorite impact is often cited as the cause of their extinction there are many proposed mechanisms at work and since we don't have time machines or superintelligent hyperhumans, we can probably only speculate. But the chunk of rock that smashed a pock-scar in the Yucatan probably did play a huge role. wD40-D6 happens to equal w34.

9KA(two uppercase letters that can be used to indicate tearful eyes)-(One of the MegaMan X series' protagonists whose name is a number)C9IZ-C2(Roman for ten)4M

Answer: QQ is actually something I learned from this site, as a common response to the sorts of 'gibd awai 3 gaymz n got $30 CV...HOO STOLZ MY SEEVEE!?' threads. Those were the letters used to indicate tearful eyes. The Megaman X protagonist was of course famous nothing, Zero and Roman for ten is X. Roman for thirty, incidentally, is XXX - and it is the Final Fantasy game I am most looking forward to in the future, but shall probably be disappointed by if it's not merely a live-action, oiled up, FF-character cosplay, fanservice fuckfest.

Get 'em while they're hot, those of the ninjutsu powers persuasion and do me the common courtesy of saying thank you. If you indicate ungratefulness through silence I will use my exceptional psychic ability to do something. I haven't quite decided what, but it shall be something of irritation or misfortune to you and when it happens you'll go "Oh bugger...I should have taken two seconds to say 'Got it, thanks!' instead of being an ungrateful little silent shitbag."

Peace, love and anthropomorphised crocodiles in funny hats.
