Undertale Tickle Stories (Main Series)

W.D. Gaster, the Best Uncle Ever Part 2 (Chapter 12)

Well, whatever highly ticklish spots that Sans and Papyrus have, they certainly didn't get from their father! Yes, the reason why Gaster didn't laugh at the end of Part 1 AND the reason why he didn't laugh in the previous chapter when the kids tried to tickle him was simply because... he's not ticklish! But he can apparently become ticklish, though; with help from this special serum he created... A serum capable of making Gaster ticklish? Can such a thing really exist? Find out in the conclusion to this lengthy part of the story! ;)

W.D. GASTER, THE BEST "UNCLE" EVER PART 2

Chapter 12: The Last Dance (of the Day)

Chara: Oh, my G-God... *uttered Chara, she and the other kids in a state of shock after hearing of a special serum capable of making Gaster ticklish, possibly more ticklish than Asriel*

Gaster: Hehehehehe. Yes, little ones, with this special serum, I will become ticklish. I will actually become ticklish... How ticklish, you might be wondering... Hehehehehe. Well, you can find out for yourselves sometime after lunch... Hehehehehe. If you battle me, that is... *stated Gaster casually, acting as if battling against children isn't anything out of the ordinary*

Oh, of course Gaster isn't planning to simply let the kids walk up to him and tickle him after injecting his soul with his special serum! No, that would be too simple! Too simple for four kids that are not only adorably ticklish but also skilled fighters. And for skilled fighters such as themselves, Gaster feels that they should earn a chance to tickle him during a time when he's actually ticklish, by battling him; not enduring more than one hour of outlandish tickles, because they've already received their reward for doing that; battling him! In a similar fashion to how Blooky, Mettaton, and Muffet battled him Friday evening and how Toriel, Asgore, Sans, Papyrus, Undyne, and Alphys all battled him Saturday morning! And do the kids have to actually defeat Gaster in combat in order to earn a chance to tickle him? Well, no, not necessarily. And is Gaster himself planning to let the kids know that they don't necessarily have to defeat him in combat in order to earn such a chance? Nope! Not at all! Because if the kids are under the impression that the only way they'll be able to tickle Gaster after he's injected his soul with his special serum is to defeat him in combat, then they'll be far more likely to give it their all during their future battle! ;)

Frisk: Wait, wait, wait, wait, wait, wait! The heck did you just say?!

Gaster: Hehehehehe. You heard me, young princess. If you want to tickle me in, oh, let's say at least 12 hours from now, you and your siblings and MK are going to have to go up against me in a fight. Hehehehehe. Blooky, Mettaton, and Muffet did Friday evening... and then the following morning, Toriel, Asgore, Sans, Papyrus, Undyne, and Alphys. Hehehehehe. Yes, all nine of them. So, it's only fair that the four of you get a chance to do the same.

Asriel: Wait! Mom, Dad, Sans, Papyrus, Undyne, AND Alphys?! They fought you?! They actually fought you?! *asked Asriel, both surprised and ecstatic to hear that the aforementioned adults battled against Gaster; though, especially the latter due to suggesting to the six of them to go up against Gaster in a fight without any knowledge that they had already done so*

Gaster: Mm-hmm. Yes, in the forest, while the four of you were sleeping. Hehehehe. Yes, remember earlier at your father's house when the seven of us told you that we were simply exercising in the forest while you were all asleep? Well, we lied... We were fighting. And like Blooky, Mettaton, and Muffet Friday evening, they lost.

Asriel: Pffffffff... Hahahahahahahahahahaha!! *Asriel suddenly burst into laughter, recalling the moment when Toriel, Asgore, Sans, Papyrus, Undyne, and Alphys all "noped" out of Asgore's primary living room after suggesting that the six of them go up against Gaster in a fight* Oh my gohohohosh, that explains so much!! Hahahahahahahahahahahahahahaha!! XD
