The Blupi/Eggbert "phenomenon"

[Revan]

Blupi, also known as Eggbert, is a yellow oval-shaped fellow created by Epsitec. He appears in several programs made for the Smaky. The English equivalent of these games were for the DOS. Many of the more recent games he has been in though, he has played a lesser role.

Most known games with him:

Blupi At Home
BlupiMania Series
Planet Blupi
Speedy Eggbert Series
Smaky Infini

This character reminds my childhood.
