We often discuss these reskinned 4 star birds in other threads so I figured they deserved their own. This is geared mostly at the newer players, and as a bit of history, plus it might shed a bit of light on why us old timers really don't bother trying to obtain most of them, seeing the majority only differ from their former versions ever so slightly. So in the beginning there were 16 four star birds. These were as follows: Red- Bette, Billie, Darlene Yellow- Brenda, Doris, El Gigante Black- Carson, Kowalski, Kowalski the Elf, Zain White- Jacquie, Jimmy, Owlpheus Blue- Paige, Ron, Trey The first to become a 5* was Kowalski the Elf. He was the second hatch in the 2016 XMAS event as a 4*. When the XMAS event came around for 2017 they had removed the 4* version from the game and re-released it as the 5* version we know today. Next came El Jefe in the Cinco De Mayo event around 5 May 2018, as a 5* variation of El Gigante, but they left the 4* El Jefe in. The trend of leaving both the 4 and 5* versions in carried forward from here. We didn't see another conversion until Carson came out as a 5* and with a Master version in August of 2018 in a black excavation event. All three hatches were Carson, starting at 25x for the first in the line being the 4*, and then the 5*, and Master 5* as 2nd and 3rd respectively. At this point everyone was happy to have a 5* version of one of the best birds in the game even as a 4*. Another lengthy dry spell and suddenly Brenda shows up as Brenda X not quite two weeks before XMAS 2018, as the second hatch in the last Chuck/yellow excavation event. The new version brought forth a Claude like leader ability, and maintained her former versions skill of ignoring obstacles. Zain, another great 4 star, appeared in his 5* version January 2019, in an event format similar to how 5* Carson was debuted. Hatching again started at x25, with the order being 4*, 5*, Master 5*. Then we saw 5* Owlpheus appear towards the end of January 2019 as a second hatch in the latest Matilda/white excavation event. The recent Chinese New Year's event held January/February 2019, brought forth the 5* Doris as the second hatch. Now for the first full week of February 2019 we have Billie making her debut in a red excavation, again as all three hatches like Carson and Zain before her, and likely the hatching will start at 25x like before. The next likely candidate to come out in either the "all three birds" or "2nd hatch" schema is Ron in his 5* version, seeing he was explicitly called out in the v2.0 patch notes and has already been obtained from EM by a few lucky enough to get to the 70th floor that night. The remaining seven yet to be seen will trickle out over the coming months, as all of them were added to the collection house during the v1.26 update. Some are worth having, others not so much. Some come with new leader abilities and new skills, other only come with an extra star and the little bit of stat increase that provides. One way or another though they all will come at some point, and pretty much like every other bird will come back around.
