While replaying Monster Rancher Evo for giggles, I am in the midst of creating a Google Spreadsheet log of Monsters that can be raised from the various discs I still own. So far, I've discovered that Katamari Damacy can unlock the Sampler for Monster Rancher Evo. Stats are; Pow 1 Int 2 Spd 1 Acc 1 Def 2 Lif 2, with an obvious advantage in Int and Lif. I have yet to recreate it as I do not have the DVD anymore, but I also recall being able to create a PieRipper with the first Pirates of the Caribbean DVD, though that may change depending on the version you find.
