This comment is interesting (as well as the other 2 children saying they also use Pokemon for host names), as there has been a study about how kids had fantastic abilities at recognizing Pokemon, but could not achieve the same levels of memorization with flora and fauna: http://www.ncbi.nlm.nih.gov/pubmed/11924673

This inspired a researcher to create a card game similar to Pokemon, but for our biosphere: http://phylogame.org/
