The items at the bottom are splits, to mark progress. Since it's a new save, the player is first tasked with completing the tutorial, then make 3 deliveries to the jungle (1 bomb, 1 rope, $10,000), then 3 deliveries to Ice Caves (2 bombs, 2 ropes, shotgun), then 3 deliveries to Temple (3 bombs, 3 ropes, Gold Key). The splits end as soon as the sound is triggered by the final delivery.

Mind explaing what all the items at the bottom mean confuses me.
