The one on the right is Dededes's design. An innocent mochi maker who wants love and control and that latter part tends to overwhelm the former. Uses her cute looks and charms to try and manipulate people. Basically, a cute but horribly annoying brat.

The one of the left is mine, who I ended up making shiny to be separate hehe, plus the colours fit him good. Based more on the Momotarou legend part. Someone who believes that he is a true folk hero but every possible good deed or wish he grants is immediately ruined by his twisted manipulation. Wonders why he isn't a beloved hero yet, so he's a bit delusional...
