At left, Princess Presto. At right, Super Why. So she says.
My daughter has dubbed one of her Little People figures "Super Why". She named the girl with glasses Super Why before she'd even seen the PBS Kids show, but saw a promo after one of her other PBS shows. Apparently, the glasses look enough like a superhero mask to her.
Later, the African-American figure was dubbed "Princess Presto". Even though the only resemblance I can see is their skin tone.
The figures do have a bit of gender ambiguity, and I appreciate her imagination, but she seems very confused about which ones are boys and girls. Very confused indeed. But we're playing along and help her find Princess Presto and Super Why when she needs to locate her "friends".
In case you want your own Super Why and Princess Presto, I found out their real names are Maggie and Michael, and you can find them here: Fisher Price Little People Michael, Dog & Maggie Figure Set
