What is the hardest moshling to get

Oddie - because he shares the same code as snookums snookums is any Star Blossom any Star Blossom and any Star Blossom while the code to catch Oddie is Purple Star blossom black star blossom and yellow star blossom (both have all 3 seeds as star blossom) so if you get lets say... 2 of oddies code purple star and black star and the other seed wasn't right you'd get snookums and if you choose to set him free to continue trying to get Oddie the plants (I THINK) will automatically dig themselves up and you will have to start again
