I did the best I could 
without spending a single yen!
Ich habe mein Bestes versucht,
ohne Geld für Zutaten auszugeben.
¡Hice todo lo que pude sin gastar nada!
¡He hecho todo lo que he podido
sin gastar nada!

j’ai fait de mon mieux !
Ho fatto del mio meglio a costo zero!
Eu me esforcei muito pra não gastar!
И притом не потратила
ни одной иены!
