Nice worm animation! But I think that it should be more difficult, I can just probably go on for hours and get bored. Maybe have 2 or 3 lobsters?

I doubt that there is another way. But I would recommend just taking the worm image from the original crab scenario and modifying it so that the worm sticks out more every frame.

In the end it says "remaining lifes", not "remaining lives". I might be able to make an animation of a worm coming out the sand using the GIMP (by modifying the worm image from the original crab tutorial scenario). And if I can, how do I send it to you?

I opened the scenario in Greenfoot and again just couldn't get through level 8 until I removed those heads moving side to side. Level 9 was very difficult but I managed to get the flag in a few tries.

I decided do do a little rewrite of this because the code was getting messy, and I thought I could take more advantage of Java's polymorphism, I might post it soon. But I am still having a hard time finding a good explanation of the physics involved...
