this code lets the Crab sprite jump up, left, and right.
Now let’s animate the crab’s movements. the Crab sprite
has only two costumes, crab-a and crab-b. We’ll switch between
these two costumes to make it look like the crab is walking.
We can simplify the set correct costume block for the Crab
sprite a bit.
Modify the set correct costume code to look like the
following:

Notice that the numbers in the floor of 1 + frame mod
2 blocks have also changed. the first costume is costume 1,
and the Crab has only two costumes, so the numbers in these
blocks have been changed to 1 and 2.
finally, we need to create a new script so that the crabs
can steal apples from the player. add this code to the Crab
sprite.
