It is possible to collect a shrimp and die to spikes at the same time (might be same frame?).
It is possible to touch a smileyface, and not receive a double-jump reset. This might be because the bird turns into a shrimp at the same time the smileyface is touched. (this seems possibly intentional).
You can bounce off the floor/spikes as a red shrimp, collect a honey walnut shrimp, then land to collect the shrimp. Epic.
The "last three shrimp" is truly amazing level design. 
the smiley face jump reset will only activate if you still have at least 1 flap left. its "intentional" but really it was just a workaround for my messy code as refreshing flaps in ball mode caused buggy behavior that i didnt want to waste time properly fixing. glad you like the three shrimp room i was kinda proud of that one
