Don't usually tackle this type of puzzle and struggling with some clue, e.g.17d fog on river or lake initially or strong wind M///R// Is it mist something?
13a Earthy animal having one other moving target
(4,6) /L// /I/E//
Presume Giddy blonde and Creepy scab are anagrams?

[sarumite]

17d Mist ral
13a Clay Pigeon

[sarumite]

17d Mist (fog) + initials of (r)iver (a)nd (l)ake

[sarumite]

12 down is an anagram of Creepy scab

26 across is another term for giddy blonde, first word "light"

[LEICESTERSHI]

but if 17d is Mistrat(thanks for the explanation too), dizzy blonde cant start with L?

See it now the fog and river one is MISTRAL _ kind of wind - thanks for putting me in that direction
