Berbils:The RoBear Berbils were the first friends the ThunderCats made on Third Earth. They helped build Cat's Lair and later the Tower of Omens. They grow a variety of fruits that they share with the ThunderCats, and any good citizen of Third Earth. the Berbil fruit is the only native food that's not poisonous to the ThunderCats. The Berbils are teddy bear-like creatures from the planet Robear which is over populated. I think Robear bell is the mate of Robear bill, I said I think she is I'm not sure. They are basically harmless and are frequently preyed upon by the Mutants and Lunatacks.
