I recently stumbled upon it, can't remember where, though. I'll do a search quickly.
EDIT:
Check out
public function siggy() in levelup.php
You should find this a few lines down the function:
PHP Code:
// Build text for siggy
$str1 = "Name: ".$this->adopt->getName();
$str2 = "Owner: ".$this->adopt->getOwner();
$str3 = "Click Here to Feed Me!";
$str4 = "More Adopts at:";
$str5 = "www.".constant("DOMAIN");
