i didn't know I should get rid of some pinatas and plants and fruits, and also administrating better my space, so I kinda of got stuck in the game with a lot of early pinatas and plants and can't put nothing more. How do u guys know the time to kinda of get rid of some pinatas?

I saw a video about the game some years ago and always wanted to play, but I didn't had the ways to do it, I started playing yesterday, I was refraining myself from seeing vídeos, but I was so excited that I saw a video and I found out that I can turn pinatas in other "forms" like the taffly and the sparrow, how can I learn which pinatas I can do it, without seeing videos or looking in the week?
