The ol' memory must be failing me, alas. The above SOOTY figures (completed today) are listed on a couple of sites as being giveaways from KELLOGG'S in 1973, but I'm sure I had some of them before I moved house in June 1972, so I'd date them around '70 or '71. Is my recollection playing tricks on me, or were they possibly reissued in '73? Anyone know? The other figures in this post came out around 1970, so maybe I just automatically (but erroneously) associate the Sooty ones with them. Anyway, I'm sure my inability to recall the exact year will bug me more than it does you. (Note that SOO is spelt as SUE on the back of the packet.)

Next up (above) is CRATER CRITTERS, which are arguably the ones that most folk more readily remember. I had most if not all of them at the time, but the ones above I bought from regular reader PC a few years back, who sold them to me for far less than he would probably have got for them on eBay. I don't buy things to sell on, so he knew I wasn't going to make any financial gain from his loss. My favourites were BUGSY BACKBONE, LUNERTIC, and JODRELL JIM. Quite liked GLOOB as well. I'm keeping my eye out for others so that I can get a more varied colour scheme.

Finally, we have NEPTUNE And His SEA-BED SERENADERS (above). In the UK we were offered only 8 figures, but in Australia (where they were issued first, I believe) there were 15 of them. I also bought these ones from PC, who lives in Australia, so I'm very lucky to have the full set. Sharp-eyed readers will have noticed that I've replaced the photos with fresh ones (yes, pun intended), so FREDDIE FISH is now facing the right way. I probably had a few of these figures back in 1970/'71, but the one I most remember is NEPTUNE.
If you had any of these sets when you were a kid, feel free to reminisce to your heart's content in our crazy comments section.
