Godzooky items of any type are a rarity, but one thing to note about these guys is that they are exactly the same size. Godzilla is standing, though, which was probably an attempt to differentiate them, and enable him to sort-of stand over his sidekick (who Hanna-Barbera production notes identify as Godzilla's cousin). When you think about it, though, it would be dumb to produce a plush two inches high, and kind of screw up the idea of packing them together.
By the way, they did indeed ship together, in a cool counter-top box. You can see dealer catalogs at the great Plaid Stallions that show you the box, but here is what the header card looked like:
