Caillou is a Canadian show that ran from 1997 until 2010, In Spain, Caillou aired on TVE's Clan channel and Canal Panda, but there was another airing of the Castilian Spanish Caillou that aired on Playhouse Disney Spain (Now Disney Junior Spain) and the Playhouse Disney block on Disney Channel Spain, It's unknown when it started airing or stopped airing, It possible that it stopped airing when Playhouse Disney Spain rebranded into Disney Junior Spain, but that isn't the case, It's possible when 2011 was rolling around, Caillou stopped airing on Playhouse Disney Spain.
Updates
- UPDATE 1: I found a Playhouse Disney Channel promo from Christmas 2010 and has Caillou clips in it! (Written by Elliottwiki12345)
Evidence
Playhouse Disney Spain - Christmas 2010 - promo
The Christmas promo from 2010 which features clips from Caillou's Holiday Movie, Where I assume it is Caillou who speaks at the beginning of the promo, And one part where Boris speaks, And lots of parts where they don't speak at all.
Playhouse Disney Spain - Merry Christmas - 2010
Here is another promo from Christmas 2010, In the end, A part of the Elastic Rights logo is shown before cutting off, If you don't know, In Spain and Portugal, Caillou is owned by Elastic Rights, It's either the opening for Caillou's Holiday Movie or a Caillou Episode.
Televisa
This isn't evidence but I will press on, Here is a Disney Channel airing with the Elastic Rights logo, But it isn't Caillou, It's Patito Feo, Which means Ugly Duckling in Spanish. https://en.wikipedia.org/wiki/Patito_Feo
