The panel initially thinks of Evi Hanssen, Connie Breukhoven, Holly Brood, Yvon Jaspers and Marijke Helwegen, but they are completely wrong. None other than multiple Olympic champion Anky van Grunsven appears to be in the suit.
There are already many hints that point to this. For example, the Bon-bon says that she likes a bit of bling-bling and that was about the prizes she has won. There was also a royal cloak and a crown on display, which was a reference to the royal honors she has received. The accompanying petit fours refer to her children who traveled with her. She also talks about a boot, which is of course a permanent part of her outfit at the time.
The panel initially thinks of Cornald Maas, Beau van Erven Dorens, Henk Poort, Frits Sissing and Marco Bakker, Henk Poort, Roelof Hemmen, Beau van Erven Dorens, Frits Sissing and Renze Klamer and Özcan Akyol, but they are completely wrong : none other than Albert Verlinde appears to be in the suit.
There are already many hints that point to this. For example, the Pufferfish indicates that he occasionally puts on his spines, because Albert can sometimes come across as vicious. Cheerful was also given as a hint, which refers to Albert’s infectious laugh. Elfje was a reference to his sister-in-law Isa Hoes who had died earlier in The Masked Singer was an elf. The word seat was also a hint, as Albert himself also sat on a seat in the municipal council in Vught. The jellyfish referred to his nickname Kwalbert Verlinde.
