Several of his insane friends are either a nuisance to Nero and co, or even a dangerous threat. All in all Nero and his friends do consider Tuizentfloot to be one of their closest relatives. In ""Nerorock" (1990)" Nero starts a rock band and Tuizentfloot is hired as their drummer, seeing that he is ""crazier than Animal"". When Tuizentfloot is shot by Ricardo in ""Het Spook van Zoetendaal" ("The Ghost of Zoetendaal") (1979)" Nero is even honestly angry and upset. He tells his wounded friend that without him the Nero stories are like ""beer without foam"". Tuizentfloot has also saved Nero many times against criminals who dared to attack him. In ""De Adhemar Bonbons" ("The Adhemar Pralines") (1989)" Tuizentfloot is transformed into a baby, so we get an idea what he looked like at that age. In ""Daris Doet Het" ("Daris Does It") (1978)" it is revealed that his mother hailed from IJmuiden and his father from Springintveld (a non-existing place which is a pun on the Dutch term ""spring-in-'t-veld"", used for enthusiastic people.) This would make Tuizentfloot partially of Dutch descent. He also has a sister, Dina, who is a radical feminist and also wears a pirate hat on her head. Two of his uncles were apparently rich and left him their fortune twice  Tuizentfloot fell in love with Prinses Lovely in ""De Mosterd van Abraham" ("The Mustard of Abraham") (1973)", but, despite wanting to marry him at first, she eventually rejects him ""because his moustache is too long and his socks too short."" In ""De Gladde Figaro" ("The Slippery Figaro") (1991–1992)" he wants to marry Madam Pheip, but she too rejects him. Tuizentfloot usually gets on well with animals. In ""De Granaatslikker" ("The Grenade Swallower") (1957), "Het Wonderwolkje" ("The Magic Cloud") (1960)" and ""Kouwe Kwibus" (1967) ("Cold Weirdo")" he respectively uses a pig, a pelican and a giant mosquito as his personal mount. Still he can attack and kill them too, like the snake and tiger in ""De Kat van Katmandu" ("The Cat of Catmandu") (1978)".
