The story is odd to me cuz I don't exactly get the joke, LOL. But aside from that, this is VERY well done! The characters were drawn and colored in VERY neat! I also like the second panel is funny because of their expression as well. Surprise is supposed to be Pinkie Pie's "Beta" self before she was changed to what we know as today. NEVER have a cute pony as a plumber. Who knows? Maybe they will put Surprise in an MLP:FiM episode someday. ... And now I can't think of anything else to say, but... keep making funny comics!
To be honest i really liked this, I love Luna and the whole fact that you tossed Derpy in there made it even better. Very original and funny, especially the "having trouble with the pipes" joke... let the pervy minds flow. Now i can say that the artwork its self was very good as well, I like it a lot and it gave me a good laugh. And everyone knows Luna is the best princess. (you know its true) I think it was very well done all around to say the least, keep it up. I expect to see much more from you.
Celestia fucked up the plumbing again?! This habit of hers has already killed dozens, including Fluttershy's parents. For the love of Madoka, someone cut her off from the cheesecake before she wipes out her rac--
Wait, what am i saying? Someone give Celestia more cheesecake! Let the ponies die in the literal shit storms!
remember those vending machines where you put some coins, then you get an egg, and then something like flubber/mucus/ egg yolk comes from it?, then you can play with it and comes in bright colors... sometimes it even shines in the dark... that got commercialized and called GAK... it seems those guys were playing with it and forgot to use less dynamite in the sewers...
