As far as I can tell, creator Philippe Coudray has been telling stories about this bear for some time - he's called Barnabé in French, and some of his stories were translated as "Benjamin" a few years back by First Second. These three books from Humanoids - I've already covered Vol. 1 and For All Seasons - may collect some of the same material as the First Second volumes, or may be entirely separate. But, either way, this is a world Coudray has returned to over a period of time: this book lists original copyright dates of 2012-2019, and was published in English (translated by Miceal Beausang-O'Griafa) in 2020.
That gets me to Bigby Bear, Vol. 3: The Explorer. It contains ninety-nine single-page stories about Bigby, often featuring Rabbit, who I guess we call his best friend. There are other rabbits, small bears, and other creatures, too: Bigby has a fish and a bird (non-talking, most of the time) as pets who are part of some gags. Bigby's explorations include space, in rocketships sometimes shiny and modern and sometimes rustic and handmade, so there are aliens a few times as well. Oh, and a Yeti. And even a few humans, just in case we thought we had a good sense of how this world works.
I should say that Coudray clearly made these stories originally for younger readers. They're inventive and fun, with a delight in reversals and transformations, often wordless and never very wordy - though Coudray, or maybe Beausang-O'Griafa, doesn't avoid longer, more complex words and ideas; I just flipped randomly to one about an Electroencephalograph. There's also a vague sense of education or learning - the smaller creatures look to Bigby to explain things to them, and he's spending a lot of this particular volume going to new places, in space or under the ocean or just further away than normal.
Coudray has a confident, simple cartooning line, with medium-bright, high-contrast colors - it's not a hugely cartoony world, but it is a somewhat cartoony one, clearly a bit simplified from a realistic view. And his pages here are quirky and interesting - pitched at a younger audience, definitely, but not talking down to them or limited to them. This is an amusing series, on a light, accessible level, full of mild but thoughtful gags and a anything-is-possible attitude.
