I like the headcanon that Tangle's tail has "a mind of its own" and performs actions based on her emotions without her consciously making the decision to do something sometimes
So have some Christmas Gays™
Blaze is probably allowed to combust LMAO
And Tangle looks like she's about to stuff the gotdamn plant into her mouth to save herself more embarrassment than she's already experiencing

Happy Christmas Eve Eve btw y'all o 0 o (or Christmas Eve if you're in a different time zone LOL)

Blaze — SEGA / Sonic Team
Tangle — IDW
