Was their accally an el tigre sason 3 in production before it got cancelled?

There was no official announcement of an El Tigre season 3 in production before its cancellation.

While there were fan desires and speculation, the show's creators and studio, Nickelodeon, never confirmed or denied plans for a third season.

It's worth noting that the show's final season, season 2, had a shortened episode count compared to the first season, which could suggest a possible ending point, though it is not confirmed as such.
