I haven'T seen him as well but then... since the update I play on a map without random events so he wouldn't appear in that game anyways.

Event or quest? I got the quest for the apiary in a 0.75 game. I've only seen one of his random events total in ~50 hours of LH play, pretty sure it was in 0.51, only ~5 of those 50 hours were spent in 0.75 though so I can't really say if there's a difference.

Edit: He's the riddle guy right? I'm not very good with names.

Have seen him in a 0.75 game. But he now asks 'what's in my pocket?', which I thought was rather unfair. At least the quest reward was good.

...

Part of the above isn't true. But I did see him, and found him in a hut as @roy berube above says.

"What's in my pocket" is actually a LotR reference or better a The Hobbit reference to Bilbo questioning Gollum under the Misty Mountains.

I also did get Mimbly when doing random quest maps.

Also whats the point of the riddles? I always click the first one and its always correct ...
