On the e-book's release day, the translator, in appropriately whimsical form, filmed himself announcing that it was now available, including information on how to find the audiobook version:
Marek Kazmierski is an award-winning writer and translator. His new Brzechwa translation comes soon after the release of his hand-bound English version of Adam Mickiewicz's Fables and his translation of Jakub Żulczyk's Blinded by the Lights on Legend Press.
Details about how to obtain the Professor Inkblot's Academy e-book are available from GiveTheWorld.org.

N.B. The original 2013 article found at this URL address was about the European Commission's plan to translate many different famous books from around Europe, including 17 Polish ones, among which was 'Akademia Pana Kleksa'. Unfortunately, that programme did not deliver the expected results and many of the books listed at the time have not yet been translated. More information about these ongoing plans (and other translation grant opportunities) may be found on the original source sites Education, Audiovisual and Culture Executive Agency, Creative Europe and The Polish Book Institute.
