Shiku is a yellow-green (chartreuse) jackal from Sisimpur, the Bangladeshi co-production of Sesame Street.

Sesame Workshop description

Shiku, a curious jackal, comes from a long line of clever family members, but is actually very naive. He is a keen observer and enjoys discovering things for himself. He is best friends with Tuktuki and together they play make believe. Shiku collects many things like stamps, for instance.
