I'm going to fall in a pit!
It's pretty dark in here.
Do you have any light source?

What's the deal with XYZZY?
Try it.
Now try it again.

This rod. What's it for?
It's a text adventure, right?
Meaning you pick up everything that's not nailed down. (The old IF tradition.)
Pick it up, ask questions later.

The bird keeps flying away!
Maybe it's scared of something.
What do you have that's potentially frightening?

There's a snake in my way!
In some cases you have to fight fire with fire.
Or, in this case, living things with living things.
What animal do you have with you?

I can't get out of the pit!
Did you read the note?
Don't worry, there's another way out.

How do I cross the fissure?
Well, magic is present in this cave.
At times like this, don't you wish you could just wave a magic wand?
What do you have that's similar?

What does "plugh" mean?
Remember XYZZY?
Maybe PLUGH's the same kind of word.

I'm in a maze of twisty passages! HEEELLLP MEEEE!
Congratulations, you've landed in one of the two mazes! Stop groaning.
If it says "all different", it's the Vending Machine maze and can be mapped by the variations in description.
If it says "all alike", it's the Pirate's Maze and it is pretty hard to get out of.

There's a dwarf after me!
Did you pick up the first dwarf's axe?
Throw it at the dwarf.

My lamp's going to go out!
This is not good. You can't travel the cave without it!
There's a Vending Machine in one of the mazes.
But you need to relinquish one of your treasures to use it.

There's a dragon blocking my way!
It asks you a question when you try to remove it.
Respond.

I can't reach the hole!
Well, this is a problem.
You may try climbing something.
Try exploring a bit.

The plant wants water!
Where's the nearest water?
Do you have the bottle?
Fill the bottle and water the plant.

I can't open the door!
Maybe its hinges aren't working.
What do you usually do with hinges?

The Ming vase shattered!
Dropping a vase onto bare ground is a bad idea.
What do you have to cushion the fall?

What do I do with these magazines?
Remember the mapping strategy at the Pirate's Maze?
That maze really had you at wits' end, didn't it?
Drop the magazines at another 'maze'.

What's with "fee fie foe foo?"
It brings the eggs back to the Giant Room.

How do I cross the bridge?
Give a treasure to the troll.
But you'll want it back.
What do you have that can return to where you found it?

What's with PLOVER and the Plover Room?
One of the hardest puzzles.
PLOVER, incidentally, takes you to the Y2 rock.
So go to the Y2 rock, say PLOVER, and you'll have your inventory with you.

Wow! A volcano! What's the point?
Nothing, actually. Sorry if you wasted your time.

There's a bear in here!
The bear looks hungry.
Maybe you should feed it?

How do I get back across the bridge?
You don't want to give any more treasures away.
Maybe you should throw him something else.
Something potentially frightening.
