I started building my amusement park and have my tea cup ride, Godzilla, cotton candy machine and popcorn machine but I don't really know what else to put in, the right side looks good but the other looks pretty empty and tips?
How about some balloons from the fireworks shows? I put a bunch in my boardwalk area last night and it really helps fill out the space with some color/fun!
Stalls could work, too, maybe with some prizes like teddy bears.
Fireworks take place every sunday in august (I think?), but you can sometimes find balloons in Nook's Cranny.
Edit: Wheel of fortune is also a great carnival item.
The colorful wheel for sure. Floor lights of all colors... Most other stuff has already been said. Maybe like the blue exercise ball as well. A colorful stereo with a song as well. Maybe balloon hats on display?
Carnival games like the duck shooting one, but could use fish models instead. Reward stand using the bears or mom's plushie. A sweets stand, can display a birthday cupcake and a sparkler (they kind of look like rock candy when displayed).
For my carnival area I added a couple stalls (It’s the diy you get from spending Nook Miles) customized to a colour scheme that I liked. On them I put prizes. Like Mom’s Plushie, Teddy Bears etc. Beside the stalls I put the Colourful Wheel so it’s almost like one of those carnival games you play to win prizes.
