We got a round birb to on our hands this episode. Or should I say heads? That's right folks, we're talking about Swablu. The true-blue, cotton-winged, bird Pokemon that just loves bein' a hat. This one's a little long as we put a lot of work in trying to make sense of some of these entries. You're welcome! Follow along with the entries below: 

Ruby: SWABLU has light and fluffy wings that are like cottony clouds. This POKéMON is not frightened of people. It lands on the heads of people and sits there like a cotton-fluff hat. 

Sapphire: SWABLU loves to make things clean. If it spots something dirty, it will wipe and polish it with its cottony wings. If its wings become dirty, this POKéMON finds a stream and showers itself. 

FireRed and LeafGreen: It constantly grooms its cotton-like wings. It takes a shower to clean itself if it becomes dirty. 

Emerald: A POKéMON that has wings like cottony clouds. After enduring winter, in which little food is available, SWABLU flocks move closer to towns in the spring. 

Diamond and Pearl: Its wings are like cotton tufts. If it perches on someone’s head, it looks like a cotton hat. 

Platinum: It can’t relax if it or its surroundings are not clean. It wipes off dirt with its wings. 

HeartGold and SoulSilver: Its wings bring cottony clouds to mind. It grooms with springwater and loves to sit on heads. 

Black and White 2: For some reason, it likes to land on people’s heads softly and act like it’s a hat. 

Sword: Its cottony wings are full of air, making them light and fluffy to the touch. Swablu takes diligent care of its wings. 

Shield: Since Swablu looks like a cumulus cloud, foes can have a hard time finding it. Apparently its wings turned white over many generations. 

BTB: It must clean. And also be a hat. It's a fluffly little friend that doesn't mind people.
