Just letting people that they changed this (at least for the northern hemisphere) as I just caught one tonight. So you can either try not to go on at night (if you are scared like me lol) or this could be used to get bells easily. Pictures below.
It seems like they aren't as rare as they used to be; I've seen more on my island in the span of 3 days than I've seen in New Leaf in the year I've played it!
They’re so much easier to catch. Move in slowly with the net until it rears up. Stop. Wait for it to go back down. Creep forward until it rears up. Rinse. Repeat until you’re close enough to net him. Easy money.
