I'll give you guys a hint >:D If you REALLY!! want to see a creature that is not in the top 15 you can do this.
ok, the following is the link for a creature in your personal status.
http://www.tibia-stats.com/index.php?akcja=showPlayersCreature&mid=XXX&uid=0000XXX is the creature ID! SO... if you change that 3 digit number you can check any creature in your database.
All you have to do is log in, and then check one of your own killed creatures, a link very similar to the above will show.
"mid" stands for "monster identification", which is the number we use for each creature, if you switch that number for the one of the creature you want to check you will open this creatures page IN your personal database (as long as you keep your uid)
Now you ask me! Ok

dumdum! But how do I know what's the ID for the creature I want to check? EASY!!!!!
Use the search function at the left nav bar enter the creatures page at the common database and you will know it's ID!!!
I'll give you some IDs to play with:

: 552

: 536

: 510

: 532

: 990
