Goo Lagoon

These are the Goo Lagoon Signs. 

In Cluefinders 3rd Grade Adventure: The Mystery of Mathra, 

there was a Goo Lagoon sign that leads to the right. 

And in Spongebob Squarepants, 

there's a Sign at the Beach in Bikini Bottom that said, "Welcome to Goo Lagoon" 

for everyone to have fun. 

Goo Lagoon was a weird, disgusting Place in Numeria in 

Cluefinders 3rd Grade Adventure, 

and Goo Lagoon was a fun popular Beach and a Brine Pool in 

Bikini Bottom in Spongebob Squarepants. 

In the real World, 

The Goo is a Substance called Brine. 

Brine forms underwater Pools of a darker Color because its 

Salinity is several Times greater than the surrounding Ocean.
