She is three times larger than the average Amanto from Planet Gorilla.
Due to deteriorated diplomatic ties with Earth, marriage between Commander Kondou Isao and the princess was planned in order to improve the diplomatic relationship between the planets. During the wedding ceremony, which requires the consummation of the marriage on the spot, Shimura Tae gatecrashed the party to presumably rescue the minors, namely Shimura Shinpachi and Kagura from having to watch such an act. The marriage ceremony was interrupted and the marriage was not made official.
In Lesson 670, Bubbles ended up marrying Kondou and she had a baby gorilla as well.
In Lesson Lesson 693 it is revealed by Matsudaira Katakuriko that after Kondo left her the previous time, she had disappeared for a while due to her heartbreak. She would fool around with "no good gorillas" living a fast and wild life. When she returned home she was already pregnant with her child Robert Gorilley Junior. The wedding is coming to a close as it is the last day of the three month long affair. During their dinner it is interrupted by a delinquent gorilla wearing a mohawk, presumably Junior's real father. Kondo believes that the difference in social standing had torn them apart and he has come to get back with the princess. Kondo tries to tell him he'll give her back but his answer fails to translate and instead comes across as a challenge.
