But I'm sure there's NO WAY the pokemon (missigno#134) shown in Kaiju Zukan could have been that weird meowth back sprite found in the leaked rom.
Maybe what we have are not leftovers of pokemon green, but a first attempt of start including new pokemon besides 151 for the the supposed bigger project pokemon Pink/Yellow sequel, then they decided to make only Yellow with the same roster.
And moving this idea to Pokemon Gold.
