Ok, a friend of mine has a rather large tank with only 3 ADF's in it, recently he bought one of those tiny remote control submarines that you can play with in the bath, or indeed fish tank.
He put it in to try it out and wizzed it about the tank a few times. One of the more inquisitive frogs came out for a look whilst the others stayed in their little cave thing. He did this a few days on the trott to see what would happen, the other day he calls me up and says 'you have to come see what this frog is doing!' So off I went.
He left the sub laying at the bottom, as soon as he put it in and it settled mr.froggie came out for a look. To my amazement
the little guy got ontop of it, my friend Tony then started the sub off slowly, raised it up a bit and then steared it round the tank with the little frog clinging on! Round and round the tank he went, then he stopped it at the bottom and the cheeky thing hopped off and swam around as though delighted with himself after his fun ride!!! 
I couldn't believe it when I saw it, apparently he's used to it now and has a go almost every day! I was worried about properllors etc but they're pretty well enclosed at the back, and the little guy knows how to ride it now!!
Weird eh?! Clever little froggie!!! Thought you ADF fans might like a laugh
