DuckTales Extended Theme but every time they say "Duck" it switches incarnation

#DuckTales
In honor of DuckTales' 30th Anniversary, I decided to make once more a musical mashup, this time featuring the extended themes of the 1987 and 2017 DuckTales, that whenever they say "Duck", it switches from the original to the reboot and vice versa. Yes, I'm actually riding the bandwagon of DuckTales memes. I can't wait for more episodes of the reboot, and I wish DuckTales a happy 30th birthday and good luck to the reboot. The first episode looks promising enough, so let's hope the whole series turns out well. And from the looks of it, I'm 100% certain that it will. Happy 30th Anniversary, DuckTales! Woo-oo!
UPDATE (5/17/19): As of now, the comments are officially disabled because I'm getting tired of people complaining about or saying that I "missed a duck" on (0:45), even though it clearly says "deduction", which doesn't count since it's not technically D-U-C-K. Believe me, it was a tough decision to disable the comments, since I enjoy getting positive feedback from others, but y'all must be crazy if you think I'm gonna delete this one and make another one just for one unreasonable flaw that people keep pointing out, especially after this has gained so much views, likes, and attention.
