Ratatouille but with shrimp

With an angry huff, Jan-Paul slammed the door of his large, extravagant home and tossed his home keys onto the table.
"What's wrong, young master?" asked a concerned maid.
He walked past her to pick up the fishbowl containing a lonely shrimp and sank into his preferred plush seat. "My uncle plans to come visit for dinner. Said he wants some cake, he does. Told him I'd have a delicious one and you know what the hondsvot does? He LAUGHS at me! ME!! Can you believe that?"
"Well, sire, hopefully the chefs can prepare an excelle--"
"No!" snapped Jan-Paul before sinking again, glowering at the shrimp. "He thinks he can laugh at ME about my food, does he? That salty dog doesn't have taste anymore. I'm gonna cook up a cake so good he'll cry!"

And he did.
Or at least, he tried.
Jan-Paul knew nothing about baking or cooking, he wasn't even sure where eggs came from. And each disaster only lead to more and more anger.
Nearby, however, the shrimp in the fishbowl watched carefully. Mr. Shrimp had always wanted to cook, and this was the closest he could get to that dream. Alas, he was close but still too far, separated by this wall of glass and forced to watch this young man waste precious ingredients.
No... No, he could not allow this to happen any longer...! With all of his might, Mr. Shrimp swam as much and as fast around his bowl as he could, and with the built up momentum he shot himself out... and landed right on top of Jan-Paul's head.
"Ah!! What in Void's name--?!" He danced around and tried to get whatever was on him off, but Mr. Shrimp was able to dodge each grab attempt. However, it was getting too close to call, and with desperation he used his tiny legs to grab on to Jan-Paul's hair. He tugged it out of fear, but to his surprise... it forced Jan-Paul to stop!
"Wh-What wicked spell do you have on me?!" Jan-Paul winced. Mr. Shrimp, curious, pulled on more of the hair, forcing the young man's arms to move against his wishes. Jan-Paul tried to fight back, but was suddenly given an idea. "Wait!" He looked at the ingredients. "Perhaps you can be of service to me..."

It took a lot of effort for Mr. Shrimp to get used to using this body via pulling hair, and maybe if he were a rat instead this would be easier, but no, he was a shrimp. Controlling a shrimp. But their combined efforts were making progress! Mr. Shrimp had watched a lot of TV during his time here (thanks to the maids putting on shows to watch while cleaning) so he knew what to do. A little sugar here, stir some there, heat it up, more ingredients, and... By the time night had come, there was a triple-layered cake sitting beautifully on the table.
"Thanks for the help," Jan-Paul grinned. "Although we both know it was really me who-- Vot! He's here! Quickly, hide!" Unable to find anything to hide Mr. Shrimp with, Jan-Paul grabbed the closest chef's hat and put it over his head.
"Yar har here I be it be me Nathaniel!" Nate announced. He pat Jan-Paul on the shoulder before looking at the cake and whistling, "That there be a good-looking cake it do be, hardy har har."
"Go on," Jan-Paul welcomed with as smug a grin as he could muster. "Have a slice."
"Oh trust me, I'll be wanting more than just a slice of this here cake," the fisherman snickered. He took a slice of the cake and inspected it. Nice presentation. It stood proudly and independently, and its icing beckoned him. He took a bite, his eyes went wide and his ears lowered. "Why, this cake... it's... it's incredible," he whispered, looking at his nephew incredulously. "Nephew, I was going to rob you, but now? Really, this cake, it's all I'll ever need."
"Thank you," Jan-Paul said proudly, clearly having only listened to the positives. He glanced up at his hat and winked at the shrimp that winked back. This was the beginning of a beautiful friendship.
