Mr. Neigh-Neigh

Mr. Neigh-Neigh or Mr. Nay-Nay is Big Daddy's fluffy pink horse pillow. Big Daddy hid it under his blankets in his bed. Whenever he woke up from a nightmare, he'd cuddle with it, but in secret.

When Mama Cosma kidnapped Big Daddy, Cosmo was devastated by the loss of Mr. Nay-Nay and only joined the search for Big Daddy to post "Have you seen this pillow?" posters all over Fairy World.

When Big Daddy is eventually found, Cosmo is overjoyed to see Mr. Nay-Nay again. ("Mr. Nay-Nay's so happy, he's ticking with glee!") But Mama Cosma had placed a bomb inside him in an attempt to low up Wanda. Big Daddy throws it away just in time and Mr. Nay-Nay explodes into fireworks above their heads.
