Go to the Distant spring BEFORE day 15. Look for a kind of flower on the map. I always do this heres what i do(works every time!): Get out 50 Red and Blue. Make sure they are all flowers. If not, power them up with the grass and rocks(i reccomend killing the blowhog and snitchbug so they wont annoy you first), and dismiss the Reds near land and take the Blues with you. Go to the flower and attack the egg. Then some kind of deformed frog thing will come out(Smoky Progg). It will ignore you until base then it will attack. YOU attack with the Blues but dont touch the pool of smoke behind it or they will die. When it gets to land get the Reds and attack you should kill it easily i reseted the first time i saw it scared the bleep out of me lol but anyway when you kill it give it to the Yellows they die major twice in the game but the other thing is look far at the flower it will have a stem its hard to miss
