The only problem, is it true they are only being sold at KayBee Toys?
Sadly, yes, they're a KayBee exclusive. JPtoys.com has contact with a Hasbro Executive who confirmed this was true. Though it is odd that some Hasbro people are saying they're officially released, while others are saying that there's no such thing.
There aren't any KayBee toy stores anywhere near me
Me neither. The nearest Kaybee is like... a two hour drive! That's what eBay is for. LOL
UPDATE: Thanks to good ol' eBay, I'll get getting the new MOC Triceratops/Human and Tyrannosaurus/Human packs soon. From the same seller, there's also a Dimetrodon/Human set right now. Anyone interested had better jump on the auction and Buy-It-Now; I doubt it'll last much longer.
