From Muppet Wiki

Bluki is one of the Muppets from Barrio Sésamo, the Spanish version of Sesame Street, having appeared from 1996 to 2000.

Bluki was a blue full-body muppet who seemed catlike in some aspects, mainly the pointing ears. He was the main star of the series during his period.

Bluki was a childlike muppet, similar to Caponata and Espinete, who made friends with all the characters interacting with him. These, in turn, encouraged Bluki to learn. Bluki was specially friends with Vera, a small yellow monster. He was also friends with "adult" muppets Bubo, an intellectual owl and Gaspar, a smiling guy.

Bluki never reached the peak of popularity of other Spanish muppets from previous periods of Barrio Sésamo.
