pasadena

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

'us location' is the definition.
The definition suggests a singular noun which matches the answer.

'sea panda swimming' is the wordplay.
'swimming' indicates anagramming the letters.
'sea'+'panda'='seapanda'
'seapanda' with letters rearranged gives 'PASADENA'.

'in' is the link.
