Spenda is right. The flop is a must call if villain is on a set of deuces. It's true that right now, we call $0.9 to win $3.05, making it approximately 3:1. If we just look at that it's an easy fold. But we have to factor in implied odds.

When the T hits, there's no way villain is folding to our shove because our hand is so well hidden. Think about it. If you are the villain and you have a set of deuces in this spot, and a T hits the turn. Now, hero checks, you bet, he shoves. You have a bottom set on a board that looks draw-heavy, but there's no way you're folding since your hand is crushes the hero's range. Hero could easily, have caught 2 pair, or had KQ and have tpgk with a backdoor draw. This means we're essentially calling $0.90 to win $11. Now our chances of hitting on the turn is 11:1, and we're getting 11:0.9, making this a slightly profitable call.

Hero also has a backdoor flush draw and an overcard which may not be good, but given the bet sizing and stack sizes, hero's priced in. Also, villain doesn't always have a set here.

Chasing gutshot draws isn't always the act of a donk as you say. Gutshot draws are usually very well disguised. And if you have a backdoor draw to go with your gutshot, you can sometimes continue on the turn with a strong draw against a made hand. If you play with proper odds, gutshot draws can be profitable.

Now as for the hand, turn is a call, river is a c/f to any reasonable amount.
