Commission for  Chistoso-TheJoke. In Spain is a very popular and much loved anime that in Japan is called Keroro Gunso, whose literal translation in English is Sergeant Keroro although in the United States it is called Sergeant Frog while in Spain yes it is called for its literal translation in Spanish: Sargento Keroro.

This anime is about some aliens with the appearance of frogs that come from the planet Keron to the planet Earth (which they call Pokopen) with the intentions of invading it and they entrust that mission to one of the groups of the Keron army, that group is led by the Sergeant Keroro who is a passionate about the models of robots and he spends much more time with his models than preparing for the invasion of Pokopen...:

Another member of this group is the young Private Tamama who is in love with his beloved sergeant.

The aliens of Keron are born with a tadpole tail, when they become adults they stop having a tadpole tail except for women who keep their tadpole tail all their lives like Sumomo and Pururu:

Because of that and because the Private Tamama usually behaves very sweet and adorable, many people believe that the Private Tamama is a heterosexual girl, but no, the Private Tamama is a bisexual boy, in the series it has been made clear that he is a boy and in chapter 108 an alien with the appearance of a human woman and with cat's ears and tail manages to seduce Private Tamama to steal the wallet, while that is happening the Private Tamama thinks that he had never had those feelings with anyone other than the Sergeant Keroro, even so, there are still people determined that the Private Tamama is a girl and they usually put as a reason the times that he has dressed as a girl, but that is no excuse: Sergeant Keroro himself has dressed as a girl many more times, either to not to be discovered, to get something or to have fun.

This drawing sums up very well what these two characters are like:

Finally a warning...: Private Tamama may be very tender and very affectionate, but he is also very, very, very, very, very, very, very, very, very, very, very, very, very , very, very, very, very jealous... his dear sergeant is his and only his... don't you dare take him off because you will regret it...
