This fanmade singamajig is royal purple with violet heart eyes, the same voice as the violet, the same harmony pitch as the tangerine, the same shirt as the bright yellow but the colors are inverted (Blue with orange triangles), red rectangle eyes, a juniper green nose, a marigold mouth, the same ears as the hot pink, the same hands as the violet and especially the same feet as the blue. She sings "Zip-a-dee-doo-dah".
Here's how she signs on, enters song mode and signs off:
Sign on: Hello!
Song mode entry: Same as dark blue
Sign off: See you later! (Same as fairy)
This is what she looks like.
