Easter Eggs

An Easter Egg is an intentional hidden message, inside joke, or feature that is concealed in the game, and there are quite a few within PMU. Some of them are listed below.

Triforce
In Grassroot Town there is a flower field made to resemble the Triforce from The Legend of Zelda. An NPC named Navi sits there as another obvious Legend of Zelda reference, specifically from the game Ocarina of Time.

Cognito
There is a hidden area in Tanren City Plaza called Cognito. This is a pun on being "incognito", meaning undercover. In 2019 a shortcut to the Tanren Undercity was added here.

Signs
There are several signs in PMU with little jokes on them.
 * A sign located Northwest of Snowbasin Town has "Sigh...n" written on it.
 * There are two signs located North of Grassroot Town. One points to the other and says, "This is a sign." while the other says "This is not a sign."
 * A sign far north of Tanren is a sign taken out of the Sinnoh games and says: "WARNING! 5/10 Pokemon faint from reading signs every day! .... and 1/1 of these signs were pure fabrication."

Waterslide
Next to Winden Range Passage is a waterfall that works as a waterslide. After sliding down it, a message appears, saying, "A waterslide in a waterfall? It must be an easter egg!"

Picasso
Near the entrance of Tanren Mansion is a Smeargle with a painting. Talking to the Smeargle gets you the dialogue, "...Art is the lie that enables us to realize the truth. Do you not understand?"

Grass Acronym
South of the entrance to Jailbreak Tunnel is a group of grass patches that spell 'PMU'.

Shaymin's Flower
Near the entrance of Mt. Barricade, directly above the Rock Smash area is a patch of flowers that plays a short tune and gives you the following message should you tread on it: "!!! Shaymin was here. Everyone else is a loser!
