Tiddlywinks starts at the snow park trailhead (see Google Maps location) and has a short, rolling climb, and then begins to descend! Most of this trail is a gradual, rolling descent with classic buff Bend singletrack. However, there are a few killer sections thrown in, including a half-mile long flow section of downhill with tons of berms, jumps (rollable or boostable), and just flow, flow, flow! This specific section isn't marked on any of the maps... just ride Tiddlywinks and you'll find it.
Tiddlywinks connects to the Funner Trail, Storm King Trail, and the C.O.D. Trail (a part of Phil's).
