The sinkhole is an old meeting place that was once used by the Mamabii Clan. It was famous for its ability to swallow up everything offered to it.
Around late 2010, Siva Prakash urinated into the sinkhole, somehow impregnating it and causing it to give birth to Siva's baby sinkhole.
The casualites of the sinkhole include:
- a random brick
- rice wheel packets
- some juice boxes of siva
This sinkhole remains a famous point in the history of the Mamabiis. The Sinkhole Almanac is a history of the group and is currently being written.
