Depressed Skeeters

Depressed Skeeters is a phenomenon of an enemy AI personalisation, that occurs in rare instances of personalised copies. Eyewitnesses commonly associate this anomaly to negative feelings of empathy towards Wet-Dry World painting, and Skeeter’s texture in general.

Description
Skeeters, affected by the personalisation, stop gliding towards Mario and mostly stay in place. Their looks become a bit messed up, as if they cried for an hour. Their eyes are all cried out and reddish, and their idle animation is shaking. Sometimes, when you jump on them, they collapse on the floor before turning into dust and coins. If Mario approaches the Skeeter, it tries to move away from him. If it meets the wall or blocked from moving further, it curls and trembles. But if it approaches water switch, it eeks in high pitch Boo death effect and skeets away from it at doubled speed. Their death sound effect is lower pitched and trembling. They don’t drop coin s and are mostly useless. In rare instances, people reported that they had a dialogue, but the information is very scarce. Mostly, it is something about the level and how it drives them insane, or how they want to break out. It is not confirmed by any sources, of course, but people claimed this happening.

Negative emotional aura
Since rare reports confirm that Skeeters are driven insane by the place, it is confirmed that their AI is affected by Wet-Dry World’s emotional aura. It is unknown how, but some people guess that their script is weak to outside manipulation. Also, they are afraid of water switches, so it may seem that their unstable legs can’t float so far off the ground. If you try to raise the water level, the game experiences a massive lag spike, since Depressed Skeeters are spawning everywhere on the waterbed in a pack of 5, and all die at the same time. Their method of dying is playing a drowning animation with intense bubble sounds before exploding, and it consumes a lot of memory to process. Level’s emotional aura browbeaten them, with reasons being unknown. But all the Skeeters are afraid of deep waterbeds and water town.

AI personalisation
This is a bit simple and more believable. AI personalises Skeeter's assets in order to prompt player empathy for Skeeter's depressed look in the WDW painting, and sometimes, texture in general. People reported feeling uneasy from the terrified and emotional look of Skeeters’ eyes, and this may be the fuel for AI to bring in this script. To add even further to the theory, some people reported having childhood nightmares of Skeeters drowning in the Wet-Dry World, and trauma stays to this day, so this may be another reason AI did the personalisation. Some people reported Skeeters dying from absolutely nothing, which may be AI teasing players’ nightmares and emotions.
