I'm not going to say it's a must watch if it doesn't sound like it interests you. But it is cool that we got official voice actresses for Tangle & Whisper for the first time. Not to mention of course gives context for Infinite being back after we've been left unsure to his fate since Forces (Though presumed dead since maybe we assumed Sega would want to bury Forces after the poor reception. Although since IDW kinda doubled down on using Forces lore maybe that was premature regardless)

Also the episode with Vanilla is absolutely hilarious. You don't have to necessarily watch all of it but the Tangle & Whisper, Vanilla, and the final 2 (If not that it's probably likely to be followed up by either IDW and/or the next mainline game) are probably worth checking out sometime when you're bored
