[He lets Izuku work on the latches, recalling the kid can use alchemy and seeing it used in a clever way.]

Good work. I would have just set a heavy rock or used lock and chains.

[Is he serious? He can't be serious... maybe.]

As to my magic... It has its limitations. I can only turn into any animal I have personally seen. It's possible for me to turn into something from viewing a picture, but it's not as perfect as I wouldn't have seen the entire body or know how they behave. There are also time limits and it comes at the cost of exhaustion unless I practice the form. I'm also limited to whatever skills of that animal, and I don't automatically know them except for movement.

For example, I could catch something as a hawk, but fighting against another one in the air would be my loss.
