A sphere with a cubical hollow inside, in which a ball rolls, so it will land with one of eight "faces" up. Pipped.
Arrived still stuffed with support material (powder). Poked an unbent paperclip into the pips to help clear it out, blew in air, bounced on table, etc. Note: White, Strong, and Flexible is also quite bouncy!
