One of the big baseball stories of 1946-47, besides Jackie Robinson breaking the race barrier, was the attempt by the Mexican League to raid the majors of its players.
That was considered cartoon fodder for John Foster, who wrote
Mexican Baseball for Terrytoons as a vehicle for that lovable two-some, Gandy Goose and Sourpuss.
And, in his own way, Foster conducted a raid of his own, lifting a joke from Mike Maltese at Warner Bros.
Warners had its own baseball cartoon,
Baseball Bugs, released on February 2, 1946. In it, the Gashouse Gorillas smack the ball to the sound of “Ahi Viene La Conga,” then director Friz Freleng cuts to a conga line.

Mexican Baseball was released more than a year later, on March 14, 1947. Foster had loads of time to borrow the gag, with Phil Scheib providing a conga tune as the Mexican bulls bat around.

One thing the Terry cartoon has the Warners’ cartoon doesn’t is Sid Raymond voicing a number of parts.
Fans of the Terry Splash™ will not be disappointed in this cartoon.
