At Sandy's treedome, SpongeBob, Patrick, and Sandy are seen eating Krabby Patties. SpongeBob and Sandy fight over the last one with Sandy defeating SpongeBob by kicking him into the tree. SpongeBob notices that the leaves are falling early and Sandy, upon closer inspection, notices her tree is dying. Sandy then decides to save her tree with science. Sandy attempts to come up with the perfect fertilizer to save her tree running into some failures in the beginning before finding the perfect one.
Sandy then sprays her new fertilizer over her tree and, in seconds, lots of acorns begin falling and they are double in size. Sandy tries to store away all of the acorns to save for Winter, but unfortunately, she doesn't have enough space. She decides to call SpongeBob for help. Sandy asks SpongeBob to dump the acorns somewhere else. SpongeBob then takes the acorns in a wheelbarrow to a different place and dumps them over a cliff. Suddenly, someone yells at SpongeBob to stop and the man introduces himself as The Shalmon. He asks why SpongeBob is dumping his acorns on his land and SpongeBob says he is helping out Sandy. The Shalmon says that the acorns are meant to be eaten and gives SpongeBob his book.
Later, SpongeBob tells Sandy what The Shalmon told him and Sandy agrees to make her acorns into food. After looking through a cookbook, Sandy decides to make Nutty Butter. SpongeBob and Patrick enjoy eating the Nutty Butter and Sandy gives them plenty to take home. Sandy is relieved to have cleared out her room of all of the acorns but is soon greeted by a crowd wanting Nutty Butter. The people had tasted the Nutty Butter from Patrick and they all want some as well. Sandy, not wanting to let anyone down, decides to grow some more acorns to make more Nutty Butter.
The Nutty Butter is a huge hit all over Bikini Bottom with Sandy even making a machine that expels her fertilizer onto her tree producing more acorns.
Sandy takes out more Nutty Butter to her customers while SpongeBob and Patrick continue working. SpongeBob notices Sandy's tree is not looking good but Patrick says that nothing is wrong. Soon, the acorns stop falling and when Patrick pokes the tree, it starts to crack up and even all of the leaves fall off. SpongeBob tells Patrick that they must do something and Patrick decides to make more Nutty Butter himself. As Sandy enters back into her treedome to get more Nutty Butter, she notices her tree is looking bad. When Sandy hears Patrick used up all of the acorns, she decides to give it some more fertilizer. However, SpongeBob tells Sandy that it's not a good idea, and suddenly, the Shalmon appears agreeing with SpongeBob. He then tells a story where he explains that Sandy shouldn't ask so much from her one tree. Sandy decides to give her tree natural fertilizer from Texas and the Shalmon decides to leave with his work being done.
