Watertight Door Lock 5:28
I still enjoy doing Ploppy’s jigsaws, seems like I’m the only one who does though?
You can alter the number of pieces to as few as you want, and choose what shapes you want too.
Where is our Mr. Ploppy anyway? Another one we haven’t seen for ages.
Hope you’re alright if you’re looking in, Plops. 
I did try to play it when it was going on, but I’m not a fan of competitive puzzles, it gets me flustered and I end up being slower than ever! Neither of them have been seen for ages, it appears - I do hope they are both ok.
Have you tried this site, Mups?
