Generate a lively and heartwarming collage featuring a girl looking like a blend of various real-life and mythical creatures. Let the similarity be akin to her appearing like a collection of stuffed animals. In her design, incorporate elements like cotton-soft fur, button-like eyes, fluffy wings, and cuddly, soft shapes. Use colors associated with adorable plushies like pastel blues, pinks, yellows, and greens. The background should be a child's room filled with other fluff-filled companions, joyful motifs, and childish decorations.
