[Cueball wakes and rises up from his pillow sitting beneath his blanket in his four poster bed with round knobs. He yawns with a hand to his mouth. Above him floats a large sound bubble:] Cueball: Yawn
[Cueball walks to the right with a small watering can held in front of him.]
[Cueball pours water from the can over the three small plants. A line goes from the water to another bubble:] Water: Splish
[Cueball walks back to the left with the watering can.]
[Cueball stops with the can right next to a sleeping cat, which has a speech bubble pointing to its head.] Cat: Z
[Cueball proceeds to pour water on the cat which immediately jumps up away from him trying to escape as water cascades on it. Again there is a line from the water to a speech bubble, but both the cats angry sound and Cueball's comment is written without bubbles.] Water: Splish Cat: Mrowl!! Cueball: –Dammit.

Stardew Valley is an indie farming simulation role-playing video game published by Chucklefish Games . Just as in similar games like Farmville and Harvest Moon , the player takes the role of a farmer who establishes their own farm and performs everyday tasks such as watering plants , growing food, and tending to animals. Pelican Town , referenced in the title text, is a fictional village in this game.
In this comic, Cueball begins his morning routine in a Stardew Valley session by waking up and watering some of his farm's plants.  However, he then walks up to a sleeping cat, pauses for a moment, then pours water on it, startling it awake.  He says "Dammit!" to this, likely indicating this isn't the first time he's made this mistake.
In the game, watering plants is an essential chore, which requires the player to "equip" a watering can.  The player moves their character up to a plant and simply presses an action button (or key) to perform the watering action.  The same action button is used to interact in different ways with other things, animals and people (e.g. to talk to them), so accidentally leaving the watering can equipped while trying to talk to someone can cause the player to "water" them instead.  The comic illustrates how easy it is to do this in the game, as well as the comedic value of seeing this happen from the point of view of the player's character.
The title text reinforces this humor by indicating that Randall has used the watering can, probably unintentionally, on nearly every person and object in the game.  It's amusing to think that he may curse each time he realizes he's still holding the can when he tries to talk to someone.  (His use of the word "Dammit" in this comic also calls to mind a brief discussion on the word in 559: No Pun Intended .)
The use of the word "virtually" in the title text plays with the word's double meaning. It is used here in the sense of "almost", however when swapping the words "virtually" and "waters", the word assumes its alternate meaning, but the title text still makes sense: Since the game is only a simulation, the player "virtually waters" his plants.
Stardew Valley was also mentioned only two weeks prior to this comic in 1790: Sad ; this comic explains why.
Interestingly, this comic is drawn in a slightly unusual style for xkcd .  Of note is the border around the caption ("Stardew Valley Morning Routine"), the thicker-than-normal penmanship, and the use of drawn borders around the watering sound effects, Cueball's yawn, and the cat's sleeping word balloon.  The cat's balloon in particular follows the visual style of the game (in which certain objects and animals may show their current emotional states with word balloons) - more generally, actions that normally occur in the game, such as the yawn and the watering action, appear to be shown in balloons while Cueball's "Dammit!" is written in the style of other xkcd comics.  This likely suggests that Cueball's epithet here represents the player (Randall) actually saying this in response to the incorrect action of his character in the game.
