I have been told you can get all the prizes if you zap teleportation at them and/or kick them until they are on the same square, then pick them all up via autopickup. Since they are deallocated as soon as you pick them up ("You hear something popping"), you better save and restore immediately.
Alternatively, you could kick them onto the stairs down, then throw items until they fall down. They aren't special anymore once they leave the level. --Tjr 00:29, 20 June 2011 (UTC)
