...and 3 other days which, I believe, are the Mystery Days

[yagowe]

On the twelfth day of Christmas, yagowe sent to me...

Twelve rebus hugging
Eleven stars painting
Ten animaniacs a-piercing
Nine anagrams flirting
Eight languages a-cuddling
Seven raves a-snuggling
Six empathogenesis a-drawing
Five ni-i-i-ipple rings
Four rain storms
Three heraldic furs
Two middle ages
...and an art in a calligraphy.
