Walter and his neighbor, Milton, two lobsters living in the ocean near Boston, Massachusetts, blame each other when heaps of garbage appear in both of their yards as they prepare for the annual garden contest.

Includes facts about lobsters, water pollution, and the Boston accent, a glossary, and ways to care for the ocean, as well as a list of organizations that do the same.

With pictures from the illustrator behind Last Week Tonight's A Day in the Life of Marlon Bundo, this delightfully punny story about ocean life, conservation, and cooperation is perfect for sparking conversations in the classroom and at home. Walt is a proud lobstah whose greatest dream is winning the annual Swell Gahdens contest. But year after year that honor always goes to his chowdah-head neighbor Milton. One day, when heaps of gahbage show up in their yahds, the rival lobstahs must join forces to save their beloved gahdens from the trash floating down from above.

Our oceans are beautiful, colorful, diverse ecosystems that are home to over a million species of underwater creatures. Unfortunately, humans are putting our friends under the sea at risk by polluting Earth's oceans daily. Lobstah Gahden will help kids understand the importance of conservation, and additional backmatter about sea life and pollution will give readers practical ways they can help preserve our oceans.
