This is one of my favourite Phineas and Ferb episodes, and I love this song, because like Candace, I’ve had a Ducky Momo of my own - my plushie Littlefoot from the Land Before Time, a movie that I identified with as a young child and into my preteen years.
My plushie is so worn because I had him in bed with me until I was sixteen, and he was always taken along on family trips/sleeping over at grandparents because he was such a comfort to me. He was REAL, like the Velveteen Rabbit story, to me.
And that’s why I love this song so much, because nowadays betraying such a love for a plushie AND The Land Before Time will probably meet with as much derision as Candace experiences as a devotee of Ducky Momo.
I can definitely agree with you here - Ducky Momo and Candace’s relationship just… reminds people of the thing that they never grew out of either… and to see such a touching love for that childhood past and to hear such a well-done song about it… it accurately depicted why we loved that thing/character in the first place: it helped us. Some how, some way, it helped us…
