I play Animal Crossing primarily in local co-op mode with other people in my house, and have noticed that we have been unsuccessful in getting Pascal to show up when playing together. I'm actually not even sure we've even found a scallop in several hours of co-op diving together. We've only seen him when taking single player turns, which causes us to break our sessions and play solo to see him.
Can Pascal appear when playing local (or online) co-op? If not, can you find scallops when playing in these modes, or was the scallop removed from the creatures that spawn underwater in co-op to avoid this encounter?
