Warner Bros. Interactive has announced two new games (Two games! Ah, ah!) based on the evergreen Sesame Street franchise. Sesame Street: Elmo's A-to-Zoo Adventure and Sesame Street: Cookie's Counting Carnival will help preschoolers learn the alphabet and math this fall on the Wii, DS and PC.

The Wii and DS games will use what WB is calling "gameplay helpers." On the Wii, that means fuzzy Cookie Monster or Elmo slipcovers that cover up unused buttons on the Wiimote. For the DS version, it's a big, clicking stylus for small, uncoordinated hands. Parents and kids alike would do well to resist the urge to jam cookies into the Cookie Monster Wiimote.
