How do I get swamp ooze?

Hint 1 of 11:

It will help to find a container to hold it.

Hint 2 of 11:

The proper container is described in the spell book from the book shop.

Hint 3 of 11:

You need to get a teacup from the Garden (next to the swamp).  It will appear
on a chair as soon as you are ready to use it.

Hint 4 of 11:

Now, try to fill the teacup with swamp ooze.

Hint 5 of 11:

You need to take advantage of the sibling rivalry between the bump-on-a-log
and the stick-in-the-mud.

Hint 6 of 11:

Talk to the bump to see what he has to say about his brother.
