Worst thing you've combed out

[brighteyes]

Wow- cat poo, dog poo, mouse poo, rotten fruit and chocolate, dead bugs???    I don't know if I could handle that.  Dead bugs would be doable, but I draw the line at excrement.

I think the worst thing I've had to deal with has been really bad tangles.

I had a Bubbles and Pinwheel with mold in their hair, Suprise with (I think) syrup drips in her hair, a random other g1 with melted rubber bands in her hair, and another g1 with a dead moth in her mane gross!! But the cat poop and mouse pee take the cake here. Super gross!!!!!

Dirt, glue, dried mud and dust... Not as bad as dead bugs though...

Wow, I feel lucky reading this thread! I've yet to deal with any kind of biological hazards in my ponies... Secondhand has only given me a little dirt, some mild greasiness, and two ponies which were rusted from the tips of their ears to the bottom of the toes. Trying to get the darkened marks out of the plugs and roots of the mane is rather difficult. A few of my deboxed G4s have had glue in their manes and tails, and a good number of my EQGs have had shocking ratnests, but that's more annoying than gross.

I'd have to say it was my experience with a recent G1 bait pony I tried turning into a custom... It's not really what I had to brush out.... but more what I had to wash out of her body that leaked into her hair. Whoever had her before me liked to store things inside the pony in question.

Rotten Fruit and God-knows-how-old chocolate. It had the smell of horror when I opened her up... Luckily, I cleaned her up good and let her sit out with lots of fabreeze and cleaning products.

This ^^^ Is OMG! worse than dead anything to me! I can do puke, poo, pee, but food??? That's rotten?! Oh....Just freaking Gross
  This pony would of hit the hands of my husband for sure! Even after it was clean I still would not be able to look at it the same way! I will throw out dishes if someone dosnt rinse them off good enough in the sink, or they go bad in fridge. My Husband has learned the hard way with his wallet  To keep the fridge clean and the sink 
Having a girly moment & squirming my arms in ewwwwww!!
