Looney Tunes

Speedy Gonzales and his Mexican mice friends are planning and setting up a fiesta and Daffy sees the decorations. The mice play dumb as if they don't see the decor. Then when Daffy leaves, he overhears Speedy continuing planning the party. Angry about this because he didn't get invited, he builds a rain-making machine which produces a little rain cloud, which doesn't listen to Daffy when he tells him what to do (mostly rain on the fiesta) and the cloud rains on Daffy. It even becomes a storm cloud and shoots lightning to give Daffy an electric shock, then turns into a tornado. After using a vacuum, which the cloud escapes from, Daffy gets sucked into the party and lands into the cake. It's revealed that it was a surprise birthday party for Daffy and he starts crying because how he tried to sabotage his own party, complete with the cloud raining on him.
