Here.

Humongous Entertainment's games used the same format for their games over time.

The file extension has a number at the end.

The files need to be xored with 0x69 for each byte in order to have the decrypted version of the files, which then need to be extracted.

Files for "Putt Putt Saves the Zoo" and 2 discs of "Blue's Birthday Adventure" are in the folder.

Thanks.

It's a sort of RIFF-like format with various chunks and sub-chunks.

Does that also decrypt the xored file? Since that's another format...

yes it checks if the archive is encrypted and decrypts it on the fly.
it worked correctly with the files you provided.
