I believe with spoiler in the title of the thread, we are safe to post without spoiler tags. However, I'll keep with the rest of the group and use them anyway.

Time of day matters:
Our little peeps will only perform certain actions at certain times of the day. Making a grande latte and practicing kung fu seem to be two of those things. They will only make a grande latte early in the morning. It requires no kitchen upgrades and no special groceries - I've gotten the trophy on a brand new family that had not even been given the free groceries yet.
The action tags are:Boob Tube - "Turning off the TV"
Care and Feeding - "Preparing a Meal"
Sleeping Dragon - "Practicing Kung Fu"
Everything In It's Place - "Cleaning the Nightstand"
Go-Pher It - "Playing On the Lawn"
That Funky Smell - "Checking Out Strange Smell"
Lotta Latte - "Making a Grande Latte"
1000 Strokes - "Brushing Hair"
Fire Stopper - "Putting Out an Oven Fire"
As far as I know, cleaning cobwebs does not require praising. I believe it is automatic the first time you clean one.
