As a kid I thought Slag and Snarl were cool, but I never saw them in the 80's except in catalogues.

I had Grimlock, but my favourite was Sludge. I played with him until his joints were looser than an alley cat on heat. He was my favourite because of how I got him - saw him on the shelf at my local Toyworld but had to save up for weeks until I could afford him. I went into the shop and looked at him every week (I would've been about 8 or 9 at the time I think?), hoping each time I went that he wouldn't have been sold until I could afford it.

I have a vivid memory of finally getting the last dollar or so in pocket money that I needed and my dad making a special trip to the shop to buy him. I was so ridiculously excited. Bought him that day and loved him from then on. One of my favourite childhood toys, easily.
