Here is today's Sun set: 30085 Jumping Snakes. The minifig is Jay ZX, who appears in five other sets. You can have too many of him, but the rest of the parts in the bag are definitely worth having plenty of, particularly the snakes, although the lime green one is the most common, appearing in four other sets.
As you can see from the instructions image, the fire-box-thingy (what is it supposed to be?) on the left has a mechanism that ejects the snakes out from the top. It's not much of a model to look at, but it's jolly good fun :-)
How have things been in your WHS? Mine has been civilised every day so far. I wonder if that will change tomorrow when the best set of the batch is on offer. Mind you, to 98% of the population, it's just another LEGO set isn't it, so I don't suppose it'll be any different...
