She's a humanoid, golden piggy bank, with dollar signs on her thighs. Penny is a professional singer, musician, and playboy model, and is therefore very flirty, seductive and smooth-talking. Due to the fact she's a walking, talking (and pretty sexy) piggy bank, she's obsessed with money. Most of the time, she doesn't wear anything else than a big, black bowtie. How her privates don't pop out, can be blamed on cartoon logic. She's nicknamed Lady Ka-Ching.
