Summer 01: Beach Opening DayEdit
On the 30th of Spring, Kai will stop by your house and remind you to visit the Beach the next day. On the 1st of Summer head down to the Beach between 1:00 pm and 6:00 pm. Everyone will be there to celebrate the opening of Kai's summertime snack shack.
Even if you don't connect your DS game to your GBA game, Kai will arrive every summer. Kai leaves at the end of the season but there isn't another festival to celebrate his departure.
Summer 07: Chicken FestivalEdit
Submit one of your Chickens to Popuri when she comes by on Summer 6, then go to the Beach between 10:00 am and 6:00 pm. If you win then your chicken will increase in its level, allowing it to hatch bigger eggs.
Summer 20: Cow FestivalEdit
Rick will stop by your farm the previous day and allow you to choose one of your cows to enter into the festival. The adult cow can't be sick or pregnant. On the 20th visit the Beach between 10:00 am and 6:00 pm to participate in the festival.
Summer 24: FireworksEdit
Walk down to the Beach between 6:00 pm and 9:00 pm. All of the eligible boys except Skye, who doesn't go to the festival, will be down on the Beach. If you are married then you can view the fireworks with your husband.
