Are they any secret missions and levels, in the Nintendo Switch game funko fusion

As of my last knowledge update in October 2023, "Funko Fusion" doesn't specifically exist as a title. However, it's possible that new games or updates have been released since then. Generally, many games may include secret missions, hidden levels, or unlockable content that players can discover through exploration, completing specific tasks, or achieving certain in-game milestones. If "Funko Fusion" is a new title or an update for an existing game featuring Funko Pop characters, I recommend checking official sources like the game’s website, forums, or community discussions for the latest information on secret missions or hidden content. If you have any more details about the game or another title in mind, I’d be happy to help!
