カラが固くなる前に強い衝撃を受けると中身が出てしまうので注意。
Damn, that flavor text is brutal; apparently, it's from the Pokémon Blue Pokédex entry. In the English translation of the game, it's rendered as
This Pokémon is vulnerable to attack while its shell is soft, exposing its weak and tender body.
but a direct translation would be something like
If it receives a strong impact before its shell hardens, its insides can end up spilling out, so take heed.
It ain't easy being green.
The artist is Aya Kusube (Bulbapedia, The Art of Pokémon), whose Poliwag was shared a few days back and who has been illustrating Pokémon cards since 1998 and has also illustrated some Pokémon books, including one about Haunter, the design of which would later be seen on her Haunter card (see some illustrations here).
There's not much info about her out there (unfortunately, her personal website is defunct and was full of Flash content that was not preserved in the Wayback Machine), but her father, Daikichirou Kusube, was the founder of Shin-Ei Animation, the anime studio best known for producing the long-running Doraemon and Crayon Shin-chan series as well as more recent anime including the pair of shōnen romcom hits Karakai Jouzu no Takagi-san & Boku no Kokoro no Yabai Yatsu and the adorable father-daughter cooking seinen Amaama to Inazuma.
Bulbapedia has this to say about her style:
Kusube's style, especially outside the TCG, is purposefully aimed at younger audiences, where characters are drawn simply and have a limited color palette. Her personal work however demonstrates her eye for detail, using a myriad of various charcoal pencil strokes and marks to define outlines and areas of shadow. The majority of this work remains black and white. This particular method is applied to her TCG artwork, many of which incorporate a solid drawing with only a few key colors accompanied with many penciled hatches or dots to define shadow.
Looking at this card as well as her others, it's pretty amazing the kind of atmosphere she's able to create with a scant few colors and some careful shading. Her Abra (Bulbapedia) is another favorite of mine.












Lmao, I love this interpretation. In light of the flavor text, I think Metapod has tired of seeing its comrades' innards be spilled and is about to even the score.
