I have lots of least favorites. I actually think I have more least favorites than actual favorites. Series 1 was by the the best series, as it did not have many mediocre Trashies... however, there were some pretty bad ones, including:
- Scummy Squirrel
- Crud Can
- Scabby Cat
- Rot Box
Series 2 had a handful of very mediocre Trashies, but it wasn't until Series 3 until we began getting very boring ones.
I just got into Series 4, and picked up two 12 packs... and got many Trashies I really don't like:
- Stuffed Chicken
- Horrid Haggis
- Hacked Ham
- Kacky Kettle (One of those very boring, generic Hard Rubbishes... we have had enough of these -_- )
Aw, Sludge Slug was one of my favorites from Series 2 :P, I liked the white color, he looked so bright and awesome, one of the few bin-sects I actually liked from that set.
A better question really is, why are all of these everyones' least favorites? I find that they try so hard to make them 'gross' that they are actually unpleasant to look at, or that they are just boring and generic.
