Enchanted Broom:
"Created by a blood elf apprentice, this broom would be extremely useful if anyone could figure out how to make it stop." <- Fantasia
Enchanted Lantern:
"Reduces the likelihood of being eaten by monsters when you enter pitch-black places." <- I think this is reference to being eaten by a grue. Grues are nasty unknown trogg things that eat your soul if you try and advance in dark places.

Snowshoe Rabbit:
"If you go chasing snowshoe rabbits, you know you're going to fall." <- the song White Rabbit, by Jefferson Airplane

"Stinker uses his aroma to repel predators and attract cats. He's much more successful with the former than the latter." <- Pepe le Pew, Looney Toons
Teldrassil Sproutling:
"It always wakes up dancing. What a happy little tree!" <- The painter Bob Ross had a tv series where he always painted 'happy little trees'.
Tiny Snowman:
"He loves to dance and wave and play with you! He melts after Winter Veil, but he'll be back again someday!" <- Frosty the Snowman
White Kitten:
""The queen had three kittens. The first gave her a juicy rat. The second, a tasty hare. And the white, her favorite, presented the head of her rival."" <- I think this is related to some fairy tale, although I can't recall which.
That's all I could figure out! Feel free to add more if you spot them.
