Penelope is depicted as an Amanda-crazed technology wiz. She also has the odd habit of interjecting the word "please" into almost all of her sentences (though in her website she puts this down to the fact that she has always been told to say "please" when she wants something, and she wants to meet Amanda). Between segments in every show, she uses some harebrained scheme to try and meet Amanda, often with the help of Drake, Josh, or her brother Preston, but never succeeds, though she is at times exceedingly close to doing so. Schemes include cloning Amanda from her toenail (but it turns out to be Drake's), having a bloodhound lead her to Amanda by following her scent, and often breaking into Amanda's dressing room. She frequently interviews people who know Amanda in an attempt to be pointed in the right direction. On rare occasions, Penelope invades skits already in progress (Most Notably 'Cooking with me' where she is chased by Security, and steals the cooking pot to try and carry Amanda with her, but Amanda comes up from the hole in the cooker). Her brother Preston has met Amanda and sometimes asks if she could meet Penelope; Amanda always says she cannot. She once shared some romance with Trevor, Barney's son, for a while. However, just as she was about to meet Amanda, she willingly gave up the opportunity and kissed Trevor just as Amanda walks by, unseen by the two. Taynt makes an appearance in the All That episode that guest starred Amanda Bynes, once again chasing after her idol.
She normally wears a vest, a plaid shirt and gray shorts, as well as large framed black eyeglasses. She wears black shoes. She has a tattoo of Amanda's face on her abdomen, which is only seen once. On the show, she runs a fansite, AmandaPlease.com, which is actually an official site created for the series.
