No, neither did I - always assumed you had to detonate them.

Equally mind expanding - didn't know that DMA went on to create GTA!

Indeed - they became Rockstar North. Their offices are still in Scotland (Edinburgh, though, rather than Dundee).

I wonder if Rockstar can sneak in a Lemmings mini game into GTA V without getting sued by Sony.

Useful trick to finish the more difficult levels with high requirements (in terms of number of lemmings to save)

I'm pretty sure there were levels that you had to do this to complete them (maybe just in "Oh No, more Lemmings"?)

That is what I was hinting at :)

Me neither! I can still remember the layout of that level where you only have two lemmings and you have to save both of them but need to use at least one as a blocker. I could never figure it out and didn't have the internet to look it up at the time! Argh!

Yup. Although, they solved this in more interesting way in Pingus. You can tell blocker to do something else (dig, build, etc.) to unblock it.
