After doing all the yard work in the hot sun and record-breaking heat, Barbie and Ken went to a near-by Vietnamese restaurant and got a mango Bubble (Boba) tea.
Barbie was glad they offered soy milk for the tea. She doesn't like the way farmers mistreat dairy cows, and so she is trying to stop drinking milk.
But sometimes she forgets what things have dairy products in them.
It was hard for Barbie to get her mouth around the big straw, and then she slurped up a tapioca 'bubble' (the dark things in the bottom of the glass are these big, firm, jelly-ish pieces of tapioca or 'boba' - Ken says they remind him of fish eyeballs).
Anyway, that surprised her and she started coughing and sputtering.
Ken thought she was choking so he tried to give her the Heimlich maneuver, but since his arms don't bend, he wasn't able to help much.
Not to fear, Barbie recovered from the choking incident without Ken's help, and since they were hungry, she ordered an order of Fresh Spring Rolls with tofu, to take home. Yum.
