If you want a free seed maker machine without paying 6,000G, befriend Daryl (crazy scientist) and witness all of his experiments in his house, there are about 4 in total. Then go inside of your House at 9:00, and go out at 9:45, and you should get a scene of him going to frost sprites house and you talking to him about the monster.(MukuMuku)As he is talking to you, eventually MukuMuku will pop up behind him, and he will notice and run away. Afterwards, the scene will end... The next day, go to Daryl's house around 2:00-4:59 and he should be talking about a seed maker machine,then he will give you one for free.
Note: you will notice when he's your freind when he walks by you and his head starts to crane towards you
Note #2: He likes,Eggs,Coins(silver or gold),fossils(any kind)
Hope this helped you guys
