Plot

Together with his friends Melissa and Zack, they will learn to not sweat the big stuff — and it's all BIG stuff. No matter what goes wrong, (and something constantly does,) Milo is prepared for every possibility, armed with knowledge, a backpack of supplies, and an endless sense of optimism and enthusiasm that can turn any catastrophe into an adventure

Phineas and Ferb crossover
