Free the Wolf Statue from its cage.

Take a picture of the rabbit outside Odin Finch National Park

Create and deploy a time capsule

Collect all other trophies

Cure the infection

Play Calvin's story again

See Johann's name in the ending credits

Find the Primary Containment Facility

Look in all peepholes and telescopes long enough to hear Edith's commentary

Clear all balls off the pool table

Let the drunken sailor finish his song

Take both paths to the house
