Mini Barks quiz - the two remaining quotes

[Daniel van Eijmeren]

My mermaid-"hint" for the second quote is too unclear and 
too confusing. So, I've added an extra hint to that one.

- - -

"Well, back into the barrel with the FLEAS!"
(Hint: "Gaaah! There's a year's crop of SOOT in that pipe!")

- - -

"Ouch! More automation!"
(Hints: "Handle with care" / "A-a MERMAID - Awk!" / 
"Somehow we never learn the beat of rock and roll, sahib!")

- - -

In private, someone guessed "A letter to Santa" and "Hall of the 
Mermaid Queen". Both these guesses are wrong.
