Beast found in China and in Pennsylvania (5)
I believe the answer is:
panda
'beast' is the definition.
(I've seen this before)
'and in pennsylvania' is the wordplay.
'in' indicates putting letters inside.
'pennsylvania' becomes 'PA'.
'and' going inside 'pa' is 'PANDA'.
'found in china' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for panda that I've seen before include "Giant, red, Chinese mammal" , "Endangered animal" , "Bamboo-eater" , "Police car" , "Bamboo-eating creature" .)
