playgroup

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

'bunch of kids' is the definition.
I know nothing about this answer so I can't tell whether this works.

'ugly prop moved around a' is the wordplay.
'moved' indicates anagramming the letters.
'around' indicates putting letters inside.
'ugly'+'prop'='uglyprop'
'uglyprop' is an anagram of 'plygroup'.
'plygroup' placed around 'a' is 'PLAYGROUP'.

Can you help me to learn more?

(Other definitions for playgroup that I've seen before include "Gathering of the very young" , "Where infants may be" , "meeting for parents and children" .)

I've seen this clue in The Daily Express.
