Looking at ngrams: angried it seems to have been most popular in the early 1800's and largely non-existent in the last century.
Looking at results for those years when it was slightly more popular, we find usages such as
- "[..] but Ahab had angried God"
- "Our temperate Sage, though angried at that spirit of contradiction [..]"
- "[..] seemed very sorry, and desirous of appeasing the angried translator"
and this gives me the impression that "angried" is an old and rare alternative spelling of "angered". See also angered vs angried.
Note that the quote you provided is in italics and uttered by a child in a novel which points to it not necessarily reflecting standard usage. See the full quote, also listed below in my edit.

There were also some contemporary usages. Examples:
Apart from these, there were some results which had in common that they

One last thing: let's look at angried vs soliloquy. Note how the rather rare word "soliloquy" is more than 10000 times more common than angried throughout the whole century.
If none of these things convince you, and you insist on these sources being enough for you to use the word "angried", that's completely fine. I would use the common and accepted word "angered" instead.
