Here are 10 perhaps strange or unexpected places to find an ooze. Some of the oozes will be very small ones, given the size of the container. In other cases, not every container material will be suitable for every ooze, so don’t put an ooze that can devour metal in a metal container. May of the places will come as a surprise to characters, and perhaps a nasty one.

1. Hidden in a sarcophagus.
2. Imprisoned in a sealed barrel.
3. In a large, lidded cauldron.
4. In the tubes and flasks of an alchemical setup.
5. Inside a hollow statue.
6. Inside a locked chest.
7. Inside a sealed bottle.
8. Inside a stuffed bear.
9. Inside a suit of plate armour.
10. When a water pump is used, the ooze comes out of the nozzle.
