poinco younger brother
(Poinco Otouto)
ポインコ兄弟 (Poinko Kyoudai; officially Romanized as "POINCO" brothers) are the mascot characters of NTT DoCoMo's Loyalty program, "D point(s)". Their name is a wordplay between "points", "inko (parakeet)" (and probably "doCOmo"). They are often used as image macros in Chinese-speaking countries.
The little brother is fat and his head feathers are smaller than his elder brother.
