Pretty Pebble

Pretty Pebble is an item produced by a domesticated Penguin after it is fed cooked fish. If the Penguin is kept fed, the pebble appears the following day as a reward item.

It can also be placed in the Stone Grinder, where it is consumed to produce random ores and opal. This makes it useful as a small source of mining materials, especially when extra pebbles are being collected from Penguin care.

• Feed a domesticated Penguin cooked fish to receive a Pretty Pebble the next day.
• Put Pretty Pebble into the Stone Grinder to get random ores and opal.
• Its main value is as a renewable source of grinder output rather than as a placeable item.
