Timmy loved Pokémon, and really wanted to enter them into Contests, but Mrs. Grimm forbade him from doing so. Instead, she wanted him to study his schoolwork and not think about Pokémon at all. Unbeknownst to her, her husband was supporting Timmy and wanted him to go out and compete in Contests. When Mrs. Grimm found out about this, she was furious, but after seeing Timmy and how happy he was, she changed her mind and allowed him to compete.
Mr. Grimm revealed that her parents forbade her from training Pokémon, and that was why she didn't want Timmy playing with them. Her Poochyena was taken away from her when she was little, leaving her heartbroken well into her adulthood as even after so long she missed her dear Pokémon. Thus she thought if Timmy never learned to love Pokémon, he wouldn't be heartbroken like she was.
But in the end, after seeing how happy her son was with his Dusclops and seeing his passion, Mrs. Grimm chose not to repeat her own parents' mistakes, and gave Timmy her blessing to follow his dream as a Coordinator, provided he kept up on his schoolwork.
| Poochyena is Mrs. Grimm's only known Pokémon during her childhood. She was forced to give it up as her parents thought that it was too childish. As a result, she was strict with Timmy focusing on his schoolwork only instead of concentrating on Pokémon as it reminded her of the sad time.
None of Poochyena's moves are known.
