bludger

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

'sponge' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'crook burgled' is the wordplay.
'crook' indicates an anagram (a crooked or broken form of the letters).
'burgled' with letters rearranged gives 'BLUDGER'.
