ok one more thing
I toadsworth (ID: 301)
But how should I toadsworth then add to level 1-2

PUTTING TOADSWORTH IN A LEVEL: It's possible put the Toadsworth in a level using sprite 301, - Select the Sprites Set Tab, - Select combobox nr. 10, - Select option nr. 8 - Toad Houses. Houwever, it is important mention: When you put Toadsworth in a level, Mario will freeze some seconds when the level starts. It's because the Toadsworth animation: he throws an item, like in the Toad House. After this, Mario can move OK. Here is a video showing the result. Sorry quality (hardware limitations). [] -P

okay I have to ask a question . Does anyone sometimes a toad moddel for Toadsworth

I assume you're asking if it's possible to load a toad model for toadsworth? I think it is. You just need to 1. Find the model 2. Export it to OBJ with MKDSCM 3. Edit 4. Turn back into NSMBD and replace.
