Tips on getting tons of bearbills.

So I was fishing at the pawpark pond when someone asks for a trade. I accept anyways because I always enjoy seeing what people have to offer. Little did I expect for my trading partner to have 4,720,650 bearbills!
Now what I am wondering is, is there any quick ways to get that many bearbills? Or what your tip is on getting a huge amount of bearville ka-ching

The way I earned my initial stockpile of bearbills -- really, I'm still living off the ones I built up in my first few months -- was to play games until it felt like my fingers were going to fall off. Mostly Photo Safari, but also the pie eating contest. I confess there was a glitch back then that made it so if you hit 'play' after finishing a game, the new round would start with all your prior points intact, meaning you'd just go up and up even if you lost.

Well, first of all, you can get 100 BB from the checklist from the Panda at the sportsplex and complete the nature walk and get 200 BB, so its like 300 BB daily. Otherwise, you can play games. Photo Safari gives a lot of BB. Otherwise, I don't really do anything. I hardly can ever spend my money.

Photo Safari it for a long time. Lol.

You can earn a few thousand in not too long.
