This is the first UltraToons crossover to have the Wayside characters.
It is revealed that Laney had her tonsils removed and as a result she can no longer do her yell.
This is the last time Tad and Chad (from FOP) appear as they are crushed when the school bus is crashed into by the St. Patrick's Day train.
Also, in this special, Blossom (from PPG) draws the ABC logo and hums three notes, a reference to ABC TV Australia's 1996 idents.
This special is a live-action/animation combo. The live-action scenes were filmed in Manitoba, Canada.
The St. Patrick's Day train scenes were filmed on the Prairie Dog Central Railway in Winnipeg. The locomotive used was the railroad's own PDC 1685, a EMD GP9. The coaches it hauled were leased from VIA and vinyl-wrapped in St. Patrick's Day decor.
Molly from the Fairly OddParents episode "Wishing Well" appear in this special.
Unlike the 3 UltraToons crossover movies, this special is a mix of animation and live-action.
