I'm a little stuck... Click here to teach me more about this clue!

'slimy creatures' is the definition.
'toads' can be an answer for 'creatures' (toad is a kind of creature). I am not certain of the 'slimy' bit.

'to get terribly sad' is the wordplay.
'get' means one lot of letters go next to another.
'terribly' indicates anagramming the letters.
'sad' is an anagram of 'ads'.
'to'+'ads'='TOADS'

Can you help me to learn more?

(Other definitions for toads that I've seen before include "Tailless amphibians" , "Loathsome types" , "Leaping amphibians" , "Frog-like land animals" , "Froglike amphibians" .)
