Tigger's adopted mom (5)
I believe the answer is:
kanga
'tigger's adopted mom' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kanga that I've seen before include "In the Forest, jumper with pouch that's" , "worn in E. Africa" , "Garment made of cotton" , "Baby whale" .)
