A user has suggested improving this page or section as follows:
"Can you actually grapple your way out of a trap, and under what conditions? How much damage does the hook do, when not pulling? At Skill levels < Skilled, are all four cases equally likely? Why is the last dropped item snagged first? On apply.c#line2568, strongmonst and bigmonst are checked for, but I seem perfectly able to harm mumakil with a hook; what do these
(mtmp)s even do? Is it possible to pull oneself more than one square?"
You can attempt to grab an item on that square, drag yourself towards a spot on the ground, attack a monster, drag a tiny monster to you, or you may end up accidentally hitting yourself (doing 10-19 points of damage). You cannot hit yourself if you are Skilled or Expert.
When grabbing an item, you will always snag the item that was last dropped on that square. Only one item from the stack at a time can be snagged this way. This can be used to snag items from the ground while levitating.
When dragging yourself towards the ground, you will only be dragged one square.
A tiny monster may be dragged with a 25% probability; otherwise, it is simply hit. Larger monsters are always hit. When grappling a monster that is large, larger or strong, there is a 25% chance that you will be pulled toward the ground instead, unless the space has water or air, in which case there is no effect. 
If you are Unskilled or Basic, there are equal chances of nothing happening, hitting an item, hitting a monster, hitting the ground, or hooking yourself.  If you are at least Skilled you can select whether you are aiming for an item, monster or the surface. If Skilled, you have a 50% chance of achieving what you try to; if Expert, 95%; otherwise there are equal chances of each outcome other than hooking yourself. If you can't decide which to choose, you may type enter to trigger a random effect.
If you get an item or monster and there is no such thing present on the target space, nothing happens.
But as for Queequeg -- why, Queequeg sat there among them --
at the head of the table, too, it so chanced; as cool as an
icicle. To be sure I cannot say much for his breeding. His
greatest admirer could not have cordially justified his
bringing his harpoon into breakfast with him, and using it
there without ceremony; reaching over the table with it, to
the imminent jeopardy of many heads, and grappling the
beefsteaks towards him.
