I like collecting fish and clothes/accessories. I also am currently trying to collect the Mermaid furniture. Previously I used to collect all the fruit furniture :3
Fishing fanatic! It's how I make most of my Bells. c: I would say furniture but I still have Nookling Junction and what they have hasn't quite appealed to my taste yet. I really need to upgrade!
It's a tossup between fish and bugs--though if it were real life I'd be more partial towards fish just because bugs are kind of gross and icky >.<
Fishing takes longer than bug catching, but they're also easier to find... And with fishing, it's really rewarding <3 But I'll go with fishing just because they make for pretty aquariums
