- Smurf Minor: 1x Swoof House
- Cassiopeia: 2x Swoof Houses
- Cancer: 3x Swoof Houses
- Corona Australis: 2x Swoof House
- Orion: 3x Swoof Houses
That makes a total of eleven Swoof Houses for the moment, though there will probably be more available once the other constellations come available.
Just like the houses of the Smurfs, the Swoof houses can be upgraded twice, once for 500 coins and once for four Smurfberries, allowing a total of three Swoofs per house. It is also possible to buy Swoofs from the build menu; unlike the Smurfs that cost 5 Smurfberries each, the Swoofs cost 10 Smurfberries each.
