Well...Elsa and Anna are very close to each other, I'd describe them as like the moon and the sun respectively, and I actually got them presents themed around that last year. Elsa has the ability to summon snow and ice back in her own and Anna's like a little ray of sunshine herself.

...[Botan that...that probably wasn't what he meant.] Oh, um, since her birthday is close to Christmas, I also figured it might be a good idea to incorporate white chocolate somehow.
