John Cena Replaces Fred Flintstone On Cover Of Fruity Pebbles

WWE and Post Cereals are expanding their marketing agreement by featuring a cartoon version of John Cena on boxes of Fruity Pebbles. The limited-edition promotion will temporarily boot "Pebbles" frontman Fred Flintstone from the cereal box covers.

A Post Cereals representative said that Kids want more variety, and Fred isn't necessarily the coolest or most relevant guy for kids.
