- Sciuro used to be a pest that invaded the Banyan Surfer, raiding larders and supplies. Lord Asculith took pity, and instead of exterminating the rodent, he first adopted it as a pet, and later elevated it as an Awakened Animal. To this day, Asculith sometimes still refers to Sciuro as "Little Shadow".
- Sciuro and Seacoil often argue about the former's penchant for hiding away supplies all over the Banyan Surfer, to the latter's annoyance.
- His name is derived from sciurus, the Latin name for a squirrel; "Shadowtail" is a direct translation of that word.
