Bit rough and ready and it'll need tidying up, but:

Islands (aka Nurikabe)

Paint some cells black (the sea) leaving some cells white (the islands).
Each given number is part of an island. Each island contains exactly one number, which is the number of squares forming that island. Two different islands cannot connect by an edge, but they may touch at a point.
The black squares form a single group of cells connected by edges. There cannot be a 2x2 region which is entirely black.
Croco keyboard shortcuts: Q or # paints black, W or - paints white.

There's been a Preisratsel already for this type, so I'd recommend trying that first before doing the U-Ratsel.

I think Q and W are also valid shortcuts (I think W = island for Weiss but I don't really remember for sure), and are easier to use on many keyboards.
It might be good to make it clear that the black cells connect along edges (orthogonally) -- seems like there's always somebody who wonders if touching corners counts on that sort of thing (even though it basically never does).

Also, in nickdeller's post above it's said that Q is for both white and black squares, which can't be possible.

OK, so now the rules are perfect but still it's not included among other puzzles in the opening post, darn it :!:

In honour of its appearance as this weeks Preisraetsel:

Pentominosuche (Pentomino Hunt) example
Place the given pentominos in the diagram so that they do not touch, not even diagonally.
The numbers outside the puzzle give the number of cells occupied by a pentomino in that row or column.

Controls:
Clicking with the mouse cycles through 1) black cell (part of a pentomino), 2) white cell (marked with an x), 3) blank
#, ^, or Q: Marks cell as black
-, /, or W: Marks cell as white
spacebar: clears contents of a cell

(Note: I don't think the German instructions currently specify anything about rotations and reflections of pentominos. I think both are allowed)
[Admin edit] Rotations and reflections are allowed.

I solved it presuming rotations were allowed, but not reflections, so perhaps that is the rule?

I noticed that the example shown in the instructions includes both rotations and a reflection, so looks like you're right about that.

Perhaps some of the puzzles will have "Reflexionen nicht erlaubt" with the puzzle size info. Same as ABCD-puzzle has no diagonal touching sometimes.

Sorry, this was a mistake. Now an other sentence is added to the instructions: Rotations and reflections are allowed. And this will not change in the future, because I dislike puzzles where one or the other is not allowed. ;)

"Höhle" (Tunnels) (lit.'Cave') example

Blacken some cells to form a cave system, which should have the following properties:
All cells of the cave (the white cells, including numbered cells) form one contiguous area.
All walls (black cells) are connected to the outer edge of the graph, that is, your wall mass, which completely encloses the white cells.
There are no white 2x2 areas.
Number cells can not be blackened.
Numbers indicates the total number of cells of the cave, including the numbered cell itself, which can be seen horizontally or vertically, from that cell.

I'm not sure we should be calling this puzzle "Cave", even though that's what the German Hoehle translates to.
It's not quite the same as the usual Corral/Cave/Bag puzzle, because of the 2x2 block restriction, and I think
because it's nearly identical to the puzzle that often gets called "Cave" in English, there might be confusion.
Something like "Corridors" or "Hallways" might be good, given the way the solutions look compared to the other puzzle.

You'll note that's the title they use as the German word for this puzzle. (See current [May 2013]) Preisratsel.
The English translation of "Cave" is, as best as I can figure "cave", though I agree it is more like a 'Corridors' puzzle...

Unfortunately this is a mistake. It should read "Höhle", but I don't want to change the applet while the leaque is running. Sorry, for confusion.

PS: When I first came across the "cave" puzzle it was with this 2x2-rule, and as I like this rule, I decided to keep it, even although I now know it's normally omitted.

I agree that we should not call this Cave, so we don't confuse beginners that might be aware of one type.
Google translate (http://translate.google.com/#de/en/H%C3%B6hle) gives 12 possible translations, and the other 11 are not already used.
"Cavity" is the closest translation, and obviously indicates a link to the 'Cave' puzzles as well. Will that be ok for now?
"Hollow" or "Hole" match the German word closely. In fact I also see nothing wrong with using "Hoehle" (we use enough Japanese names already) if we didn't have a better option.

PS Roland Voigt invented a Corridors type earlier this year, but I'd think "Tunnels" better keeps to the underground theme.

FYI, there was another, temporarily common, type called corridors some years ago. However, with no 2x2 'caverns', 'tunnels' seems quite apt. Done.

With the CrocoMarathon showcasing the 40 applets currently used, I followed the link from there to this thread and noticed our collection contains only 38 translations. Haus-Baum-Tier and Yajilin are missing.
