Jeff the Land Shark

What's more huggable than a puppy, but hungrier than a great white? It's Jeff! This baby landshark may be one of the most unusual and adorable creatures to ever waddle his way out of the ocean. But anyone who's crossed Jeff's path can tell you that behind his sweet little bark is one nasty bite!

After getting captured and displayed as a curiosity at the Collector's Theme Park, Jeff broke free when the Timestream Entanglement scrambled reality. Now's his chance to prove he's a hero, one chomp at a time!
