Some TMNT stuff really isn't for little kids.
Sheena is later seen attending martial arts practice in Splinter Dōjō.
Sheena continued to cultivate a close relationship with Jennika and spent a lot of time with her, even encouraging her to start her own band. She also convinced Jennika to accompany her to a Mutant support group meeting.
Eventually, Jennika decided it'd probably be better to give up her dream of starting a band, feeling the pressures of her leadership position and all of her duties outweigh that project's importance and bid for time. After discussing this with Sheena, the two went to martial arts class, and Sheena accidentally lost her wig when attempting a palm strike. Sheena ran off in embarrassment and Jennika ran after her to console her. A grateful Sheena kissed Jennika on the mouth, surprising the latter.
- Although the Ramones had a 1977 song titled Sheena Is a Punk Rocker, creator Sophie Campbell has stated that she had never heard of the song prior to the character's creation.
- Before Sheena was revealed to be bald and always wearing wigs, the story had already hinted at her at least sometimes wearing some sort of artificial hair by virtue of her hair appearing so much longer while performing on stage than in most of her other appearances.
