Step 4: You will now be able to play bitter sweets as a land animal, which is loaded into a den.
Effects
Because you are desynced, people can only see you in your spare's den. Even though players in bitter sweets can't see you, you can still interact with things like player pads. (if 3 other people are on player pads, you can still get the prize for them by standing on the 4th one).
If your spare switched into an underwater den, you can also play it as an underwater animal, although you can't fly over walls.
Switching to a flying animal allows you to fly over walls and into any pet passage. Other people who are in the adventure will appear for you as tiny pets with unclickable name tags. People who are in your spare's den will also appear for you as regular animals and clickable name tags. Anyone who goes off your screen will appear with an animal icon.
If you are a land animal, you need the correct pet to unlock the passages. You are able to switch pets as you have the regular game menu,
