Gift deliveries and the alien saucer.
Gift crates
A gift crate lands on the delivery pad about every 3 min. Tap it to open it. Most of the time it holds 2 min of your earnings (at least $5); 20% of the time it holds 3 Gold Foil instead. The Tin Songbird artifact makes crates hold more.
The saucer
An alien saucer flies over on average every 20 s. Tap it for a tip of 10 s of your earnings (at least $5). The Saucer Whistle artifact makes the tip bigger.
