you guys aren’t telling me if it’s big enough for my future budgie

Pacifier-a toyish thing that has hair and a bell.It is for when a bird picks out its feathers,so the bird has somthing else to pick on or sometimes used as a toy.
D stands for dimension(long)
Cuddle bone-is a mineral calcium.
Shaggy kabob-You can put fruit,veggies,and treats on it.
Acrylis Spinners-toys that go on perches.
Sand Perch-to keep the nails grinded down so there not sharp.

The toys should be plenty enough.Hope this helps!
