What's a Poke Ball? It's very complicated and I will let Wikipedia do the explanation.
The Poké Ball (モンスターボール Monsutābōru?, Monster Ball in original Japanese language versions) is a spherical contrivance in the Pokémon video games and anime television series that is used by Pokémon Trainers to capture new Pokémon and store them when not in use. The Poké Ball is also a central symbol of the franchise, and is often found on Pokémon-themed products.
So, Ryan returned home a happy boy holding his Poke Ball which "stores" a Piplip (one of the many, many pokemon characters; obviously they could not find Pikachu, the most popular and also Ryan's favourite character) while Jim burnt RM69.90 in the process.
See......if you cannot get anything from your parents, there's always Jimmy Ah-Koo and Amy Ah-Kim.
