|“||You can't lose even a single Wee Birdee when carrying them to Big Birdee. Proceed very carefully. You can't help carrying them into battle, so fight cautiously.”|
|— Daroach • Kirby Mass Attack|
Wee Birdees are tiny yellow spheres with little wings. Each Wee Birdee has a yellow curl of fluff atop its head, innocent eyes, and a small orange beak.
Wee Birdees are found trapped in a cage in the middle of the desert. They tell the Kirbys that the Gegs trapped them inside the cage and that they need to find their mother. The player must have the Kirbys bust the birds out of the cage by rapidly tapping a button with the stylus. Once freed, they will jump onto the Kirbys to be carried.
There are six Wee Birdees to be carried. The Kirbys must be careful with them; if a Kirby is KO'd, the Wee Birdee being carried by that Kirby will fly to an empty-handed Kirby. If the player loses enough Kirbys that there are less than six left, he/she will get an immediate game over.
After going through some trials and enemies, the Kirbys will meet up with Big Birdee, who is sobbing over her missing babies. Once she sees that the Kirbys have her young, she is overjoyed. The Wee Birdees fly onto their mother's back, and she flies off. With this act of good will done, the Birdees and Big Birdee will not appear again to attack the Kirbys, but to help.
- A Wee Birdee makes a cameo appearance on the cover of the Game Album. On the Extras selection screen, if the player taps the Game Album, some photos will appear; one photo shows a Kirby holding a Wee Birdee, standing on Big Birdee.
- Daroach mentions that the relationship between Big Birdee and the Wee Birdees makes him tear up.
- Even though the Birdee clan has made friends with the Kirbys after Stage 11 of Sandy Canyon, a few Birdees still appear as enemies in Stage 10 of Volcano Valley.
