In Angela's apartment there is a picture of Kachorra with red hair, which is part of the makeover she gave herself after she ran away. It would not be possible for Angela to have such a picture because she didn't know about the makeover. She like the others thought Kachorra still had long brown hair with blonde highlights.
Kachorra likes bright colored clothing and psychedelic decorations, but in flashbacks she is shown to have plain tomboyish clothes like her friend. Yet, she says she can make her own clothes and when shopping is attracted to bright colored clothes. Wearing drab clothes doesn't make sense for her character.
Kachorra calls Pirrina "Cata" when she runs into the house. This is the name of another character, and was a mistake said by the actress but was kept in the final cut.
