  We show how wormholes in three spacetime dimensions can be customizably
warped using pressureless matter. In particular, we exhibit a large new class
of solutions in (2+1)-dimensional general relativity with energy-momentum
tensor describing a negative cosmological constant and positive-energy dust.
From this class of solutions, we construct wormhole geometries and study their
geometric and holographic properties, including Ryu-Takayanagi surfaces,
entanglement wedge cross sections, mutual information, and outer entropy.
Finally, we construct a Python's Lunch geometry: a wormhole in asymptotically
anti-de Sitter space with a local maximum in size near its middle.
