If the titan transformation is immediate once a titan eats a shifter, how did Santa Titan not become a shifter when he ate Eren?


As we see from the Manga

> when Eren ate his dad and when Armin ate Bertolt, they immediately
> transformed into a shifter-titan.

But when Eren gets eaten in Season 1, how is it that the titan who ate him
never transformed. Plus Eren was inside his stomach for a while before he
transformed and killed him.




The proper requirement to gain the powers of a shifting Titan is to drink the
spinal fluid of the Shifter. This is revealed on chapter 65. The "Santa" Titan
didn't gain any powers because he ate Eren whole.

> When Eren ate his father, he bit him on the waist, severing the spine and
> getting access to the fluid. Armin bit Bertholdt on the head.
