Animal Crossing: New Horizons is a pretty laid-back, straightforward game, but there are some things that don’t quite add up -- especially if players start to dig deeper. Some of the game's major mysteries include the bizarre behavior of trash, non-recruitable NPCs' apparent lack of sleep, Blathers' ability to be in more than one place at one time and more.

On the surface, life in New Horizons is idyllic and easy, but these mysteries are hard to get past. Here are five of the biggest mysteries in the latest Animal Crossing installment.

Why Does Trash Act Like Fish?

One thing that doesn’t quite make sense is in regards to fishing. Different size shadows indicate certain classes of fish, which can help players determine if the small, medium or large shadow in a body of water is the fish they're hoping to catch.

However, players can also catch garbage, like cans and tires, or even bits of stone. It makes sense that players have to deal with some level of pollution in-game, but these objects look and move like fish in the water, which makes no sense. This also happened during Bunny Day, when the water eggs also looked and moved like a fish. Looking like a fish is one thing, but the items move and nibble at the fishing rod like an actual fish would. There's no explanation for this behavior in-game, but trash and stones are deceiving, which is super frustrating for players.

Does Blathers Have An Assistant?

Blathers runs the entire museum in Animal Crossing: New Horizons, from assessing fossils and taking in donations to -- presumably -- putting donations up for display. Everyone knows Blathers doesn't work all the time, because if players go into the museum during the day, the nocturnal Blathers is often asleep on his feet.

However, he's still standing at the entrance to the museum. If Blathers is the only one working in the museum, he would need to both be at the front the entire time and going to put the items up for display simultaneously. So, either Blathers is in two places at once or someone else works at the museum.

Do Isabelle and Tom Nook Sleep?

Resident Services also raises some eyebrows. When a player first moves to the island, Timmy, Tommy and Tom Nook all stay in the Resident Services tent, but there are no beds, cots or even sleeping bags. In fact, it doesn’t seem like they sleep at all, since the tent is open all day and night. It makes sense for them not to need beds or sleeping bags if they never sleep, but that raises another, perhaps more pressing question: Why don’t they sleep?

When the resident services tent gets upgraded to a building, Isabelle moves in. While there is a door at the back that could lead to a bedroom or apartment area, Tom and Isabelle are at their desks 24/7. Tom Nook frequently puts his coffee cup in his pocket when players approach the construction counter to speak with him and Isabelle can sometimes be seen snoozing at her desk. Clearly, if these characters do have sleeping quarters, they don't use them, which is somewhat alarming.

Where Do the Nooks and Able Sisters Live?

Animal Crossing: New Horizons

In both Nook's Cranny and the Ables Sisters' tailors shop, there are doors off to the side or near the back, but it's unclear what's behind them. These could be bedrooms or small apartments where the characters go to eat, sleep and bathe when the stores are closed, but these doors could also conceal simple storage rooms.

Given that inventory changes daily, a storage room seems the most likely option -- but that again begs the question of where these characters go when they aren't working.

What’s Up with Fossils?

Blathers offers to assess fossils in Animal Crossing: New Horizons

Fossils are great. They're easy to collect and, once assessed, sell for a decent number of Bells. However, they're also a bit odd. First and foremost, where are these islands located that more than 70 fossils can be excavated from the ground? Animal Crossing: New Horizons islands are small and the dinosaurs were, let's face it, rather big.

Second, fossils are one of just two museum item types that can be gifted to friends or dropped. Players can't exchange fish or bugs with friends, though they can exchange fossils and art. This seems less like a mystery and more like a mechanic that can simply be improved, but it's still worth noting.
