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

'legendary beast' is the definition.
'yeti' can be an answer for 'beast' (I've seen this before). I am not certain of the 'legendary' bit.

'confined to skye timorous' is the wordplay.
'confined to' indicates a hidden word (the answer is confined in the clue).
'YETI' is hidden in the letters of 'skye timorous'.

Can you help me to learn more?

(Other definitions for yeti that I've seen before include "hirsute specimen" , "Legendary beast of the Himalayas?" , "mythical monster!" , "supposed mountain creature" , "Mythical Tibetan beast" .)
