Taboo

Always with MunMun
Taboo appears to be a calm and down to earth Ufogs, always following MunMun around.
He tends to worry a lot and will make everything in his possible to sublty prevent MunMun to get itself in troubles.

But when he gets angry (usually when Taboo is in danger or hurt), better not stick around, because you really don't want to see the dangers that are hiding under his stitches.
