I just found this myself, and was surprised not to see any news about it on the boards. Anyway in level 84 there is a secret extra life

on the left side of the level. If you look at the top pear on the left side, you'll see that in his little chamber the ceiling is raised somewhat. If you jump up in there from the platform at the right, the extra life will appear. I'd recommend that you do that only once the coast is clear, because those pears are outrageously annoying. Good luck to all!
By the way, do any of the other original players still play? It seems to be all new people in the boards and I'm wondering who's still playing the English server from the beginning like me. Cheers!
