This is likely to be a short write-up because, to be honest, I’m not entirely sure what to think about how to place this in terms of the canon. As a 31-year-old reading this for the first time (especially soon after reading Akira and Even Monkeys Can Draw Manga) it is incredibly different… and not necessarily in a good way.
In a way, I don’t think I am really the best person to talk about this as it really is more aimed to be shared with a 5-year-old child. Pretty much everything in these stories would appeal to a small child, from the humour to the art style to the childish resolutions to all the plots. For example, you have Sardine (a girl who travels through space with a crew of space pirates) start an ice cream fight when it appears their sundaes have been poisoned by their arch-enemies.
Again, a cool sort of rebellious spirit that a small child might enjoy. However, it didn’t quite connect with me and so I’m just happy to have been able to cross it off quickly so I’m able to move onto whatever comic is next.
