There's a bit of a purchasing confusion going on here, certainly for console players. To get the bonus content you have to purchase the Bikini Bottom bundle. But some players are just buying both kits instead and obviously as a result they don't get the bonus items.
So for anyone on Xbox who hasn't yet purchased the content and wants the bonus items, you have to go to the Microsoft Store online or on your Xbox rather than purchase from the Sims 4 dashboard once the game is loaded. The Bikini Bottom bundle isn't on the Sims 4 dashboard with other packs. It's with other premade bundles in the Microsoft Store itself. I know many players tend to buy their packs by loading the game itself but you can only see individual packs that way, not bundles.
