Small mobile home or Beetle? (7)
I believe the answer is:
scamper
'beetle?' is the definition.
(beetle can mean to scamper around)
'small mobile home' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'mobile home' becomes 'camper' (synonyms).
's'+'camper'='SCAMPER'
'or' acts as a link.
(Other definitions for scamper that I've seen before include "Run with quick light steps" , "Run along quickly" , "Beetle" , "Skip playfully with campers" , "Proceed hurriedly" .)
