There's trouble in Bear-a-dise. Psychically sensing the rise of a new cutie, an anxious Knut has taken out his aggression on some innocent fish. Flocke, meanwhile, Flocke makes her big debut this week. In a crime BBC online calls a "shock," Knut fished out 10 live carp from his moat before "senselessly murdering" them and leaving a trail of fishy remains. He is also overweight, and as such, may invoke the infamous "twinkie defense" for his murderous actions.

Meanwhile, "younger, cuter" cub Flocke had her debut media outing Tuesday, and she'll be open to the public for the first time today. While Flocke was initially "camera shy," she was soon hamming it up for the press. She best enjoy it now. She's never going to look this good again. As Flocke takes the polar bear spotlight, a Berlin Zoo official noted pragmatically "Knut's cuteness factor has disappeared, and from time to time he likes rolling in the dirt. There is no way around it. Interest will wain."
