My Unicorn Magic Horse

Brushing, washing, and detangling the mane come before any of the fun stuff, since the unicorn starts out scruffy. A soap bar and hairdryer clear away the mess, and the mane only lies flat once it's actually been combed instead of repainted a new color.

After that it becomes a straightforward dress up round: saddles, leg wraps, and a horn charm all layer on top of the clean coat. Mixing grooming with a design game like this means the glow-up actually shows, since the before-and-after difference is the whole point instead of a single costume swap.
