Pentan is a series of penguin-based cards. They were first seen in BS02 and gain members in nearly every set. All Pentan cards are drawn by the artist, Poporucha. All of them are in the family Song Bird, and some of them are in the family Drifting Spirit. All cards are in the colour Yellow. Pentans have been favored by a few anime characters, Kotarou Tanaka, Kouta Tatsumi and Laila April.
