Day 5: Tuesday - PSYNCIN' IN THE SUSTaiN

1: Approach the Sliding Door and say "Welcome Back!"
2: Approach the phone and ask, "My husband?"
3: Approach the Cake and say, "Congratulations, Ota!
4: Inspect the Envelope and say, "Lets do our best"
HIDDEN ITEM: Under the right side of the table closest to the Odoroki-man Sticker you will find this hidden item.
ACHIEVEMENT OPPORTUNITY:
Inspect the Autograph, then select all three of them using TIMIES to unlock:

6: Inspect the Odoroki-man Sticker and ask, "Chocolate?"
7: Look at the Wall Clock and Advance Time (If you got the autograph achievement, put the bucket on your head, and picked up the Hidden Item, you're low on time but should still have enough time if you did everything fast enough. Use a TIMIE here.)
