Undertale the singing movie

3. Royal guard dogs

we now see a dog standing on two legs wearing a pair of shorts, a pink tank-top and he has a doggy treat in his mouth, his name is Doggo, he is also blind but not for long, during his time he was starting to get bored till he heard giggling from behind but when he turned his eyes to the right he got pushed to the ground with Nitro flipping into the air and falling to the ground hitting Doggo on the head making him grab it in pain with Sans running up to Doggo saying

Sans: Doggo are you okay, I'm so sorry about my friend here, he's a bit of an idiot if you know what I mean

Doggo then got up and said

Doggo: yeah, I know what you mean, when I get my hands on-

Doggo didn't finish what he was saying because he is able to see everything and then said

Doggo: Sans I can see, I can see everything and everyone, even when their not moving

Sans became shocked about it and looked to Nitro and said

Sans: boy, Nitro is a really weird human

Flowey then poked his head out from the snow Nitro got his head stuck in and said

Flowey: that' what I said when he turned 4

when Nitro got his head out of the snow he turned around and introduced himself to Doggo

Nitro: hi, I'm Nitro, you must be Doggo

Doggo shook his head but when he was about to say something he looked in the distance and remembers who it was and said

Doggo: best be careful, Lesser Dog is over there on top of that shed waiting for a human to come by

Sans tugged on Doggo's tank-top wanting to tell him something and said

Sans: if Papyrus and Undyne met him, that must mean the whole underground met him, so it probably won't be a problem, oh and also, Nitro's attack is music, look out!

when Sans ducked Doggo looked to where Nitro and Flowey are and ducked from one of the music notes.

(Lesser Dog's shack)

Doggo was surprised about what was going on but when he looked for Nitro he saw Nitro using a violin and Flowey using a tiny guitar to shoot the music notes and Lesser Dog with a ukulele, then he saw Sans entering the battle with his trombone and started helping Nitro fight Lesser Dog, Doggo was trying to figure out what to do till he saw a drum with a strap on it with a pair of drumming sticks and so Doggo picked them up and did a beat and a music note came out from the front of the drum and it hit Lesser Dog with Nitro saying

Nitro: nice one Doggo, you hit LD in the belly

Nitro then used his super music note attack to launch Lesser Dog at the shack he was sitting on top of.

Sans and Doggo became shocked about what they saw and Sans said

Sans: what kind of special attack is that?

Nitro then walked backwards until he was near the two turned around and said

Nitro: it's my final attack, I use it when the enemy is at the knockout point, anyway, are we going to keep moving forward or are we just going to stand here like a couple of treobers?

Sans and Doggo then started to laugh when they heard what Nitro said then Sans said

Sans: that was a good one kid, but yeah, we should keep going, you coming Doggo
