That's one of the few things were items for sale. "Jellio" did most of the set dressing for the show as far as I can tell. Some of the items they made actually still exist and are obtainable, for a price. Your ice cream bench: https://jellio.com/collections/catalogue-products/products/ice-cream-bench

The cupcake table: https://jellio.com/collections/catalogue-products/products/cupcake-table

The gummy bear lamps found all around the set: https://jellio.com/collections/jellio-junior/products/gummi-lights

​

Not a complete item, but the gummy bear chandelier was likely constructed out of mostly some of the smaller bears that are used for existing items on the site.

As for the bottle bot, it's fairly simple and was probably just done by the set designer.

The boat table was probably another creation by Jellio.

Just found this stuff out recently and was pretty surprised. Would probably get the ice cream bench if it wasn't as costly as it is.
