TV TYME

so we haven't had any official confirmation of Tenna's ridiculous height yet, and i haven't been able to yank sprites from the game... however. there's a handy little Deltarune height chart made by an anonymous user some time ago, which gives a rough indication of the height of each character:

crucially, we see Kris' height is 5'1.5": this is great for us, because we see Kris next to Tenna frequently!!

if we round down Kris' height to 5", we see that Tenna is approximately three Krises tall without his antennae, and nearly four Krises with them!!

that means Tenna is at least 15 feet tall, but if you count the antennae, his whole height is closer to 19 feet.

ANT-Tenna and some game accurate(-ish?) ANT Tenna. I drew him normally once and then proceeded to exclusively bug-ify him.
