Bungle joins Paddington's family for a bit of breakfast (4,6)
I believe the answer is:
hash browns
'a bit of breakfast' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'bungle joins paddington's family' is the wordplay.
'bungle' becomes 'hash' (I've seen this in another clue).
'joins' says to put letters next to each other.
'paddington's family' becomes 'browns' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hash'+'browns'='HASH BROWNS'
'for' is the link.
Can you help me to learn more?
(Other definitions for hash browns that I've seen before include "potato dish" , "breakfast? Part of it, perhaps" .)
