Subterranean Ocean ! ! WTF ?

== Just Like There Are Lava Tubes There Are Also Water Tubes ==
Groundwater Flows Just Like Lava The Erosion Creates Caverns Some of These Caverns Are VERY Large And Many of These Caverns Have Rivers That Lead Into The Atlantic Ocean However Those Specific Rivers Require A Submarine To Traverse However There Are Caves That Lead To The Planetary Surface That Humans Can Traverse Without The Need For A Vehicle Many Avox Travel To The Planetary Surface Via A Sinkhole However That Kind of A Sinkhole Very Rarely Is In The City Streets 
== That Sinkhole Is New ==
Maybe The Avox Are Tired of Having To Cross International Borders Every Time They Wanna Visit Their Homeland On The Planetary Surface So They Sank A New Hole Into Their Caverns And Their Sinking Holes All Over Panem For Greater Accessibility To The Planetary Surface 
== Another Sinkhole ==
== I Think The Avox Have Another Burrower ==
The Burrower Is A Drilling Machine Designed Specifically For Creating Sinkholes When The Avox Are Firing Up The Burrower They Are Expanding Their Settlements Further Towards The Planetary Surface The Very Existence of A Sinkhole Is Evidence The Avox Are Present In Panem
