Like the seventeenth season,

although Arc Productions had officially taken over the animation aspects of the television series, the episodes still used the opening titles and closing credits made by Nitrogen Studios. This was the final season to use their opening and closing footage and from the nineteenth season, the opening and closing footage was made by Arc Productions.

According to Ryan Hagan of SiF, the episodes in Spills and Thrills were going to be part of this season.
