Yay!!! I'm so glad that you and the kiddos like it lani!
For everyone else, the idea of my swap item was that the Doctor had bumped into a future version of himself, traveling with lani and her lovely kids. The TARDIS had cooked up a "Companion Survival Kit" for her, containing all the things a human might want while on extended trips through time and space, that the Doctor couldn't be bothered with, and a more kid-friendly one to keep her wee ones occupied on long shuttle drives to the Sapphire Waterfalls of Midnight.
The kid's survival kit:

Including crayons, a mini deck of cards, magnifying glass, pencil sharpener, 2 pieces of chocolate, and Doctor Who coloring books that I made. I actually made a PDF of the coloring books, so if anyone else wants one, you can find it at this address:
