Melted red balloon.
Years ago a friend of mine and I decided to make Barbie a comic book style outfit and since we didn't have any shiny spandex type material we used balloons. Well years later said balloons melted and a bunch of it got onto my beloved Barnacles tail and it's taken a lot of washing/conditioning and combing to bring his tail back anywhere close to its original condition.
Dead bugs have happened many times and don't really bug me too much anymore, though I do think cat poo takes the cake on worst things.

Thanks for the welcomes and advice everyone! I will definitely see about getting some photo advice later in the corral.

Thanks kiwimlp
Think that's one of my favorite customs I've ever made! I made it for a friend who was obsessed with Clipper back in our childhood days.

I miss these so much! When I was little my family would make one trip to the zoo a year (at least) and I used to always get one on every trip. The machines were changed out it seems every time I went so I was always getting different animals. I haven't seen one of those machines in years and had pretty much forgotten about them until seeing this thread. I'm going to have to see if I can find if there are any around here still.

Wow congrats! I am still a long way off from completing any of my collections yet but I hope to someday complete at least small ones if not full generations. (all Mintys, all Snuzzles, all Cotton Candys etc)
Would love to see pics.

Oh goodness that is so adorable! Now I will need to get myself a Fingerpaints sometime I know my Strawberry Swirl would be oh so happy if I brought him home. 

I'm just glad I'm not the only one who's changed the gender of some of their ponies lol. I had certain G1s being boys long before Hasbro made boy ponies.

Thanks much! I will have to see if I can get some since I've learned the hard way that acetone nail polish remover usually leads to horrible smudging.

I would love to set up somewhere nice to display my collection but since I'm not sure that will happen I'd love to at least find a nice place to display my customs. I wanna work on a custom for my sister but I'm torn on what.
I would love to do some higher quality nicer customs though I usually get too impatient .
As for what I want for my collection:
More Mintys xD I don't even care if they are doubles at this point.
Any Snuzzles that may or may not have been made besides the two I own, the original G1 Snuzzle that I got when I was a little girl and the remake they made when G3s were the big thing still. I'd love to get my hands on a mint or near mint Snuzzle and/or Minty.
I want G3 babies both to collect and to customize, they are so hard to find around here. And I would love to get more G1 babies either as collectables or custom bait.
And I'd love if I could find more of the fakies that used the G1 newborn mold. Have one of those in the process of becoming Baby Minty.
And I definitely want money that I can spend on this obsession.
Oh and a custom that wasn't made by either me or my sister.
