The best part about Halloween this year was listening to Oliver say "Halloween costume" over and over. Anything that remotely resembled Halloween he would call a Halloween costume. I guess it was extra amusing since he's only started to talk a lot in the last few months and he still refuses to say a lot of simple words (like "yes").
Elsa quickly decided to be a pumpkin and stuck with her choice. Amelia had a hard time deciding. She finally came up with a mermaid fairy. Oliver attempted our old monkey costume for a bit but had an extreme dislike for the bulkiness of the costume and at some point switched to a skeleton.
