I forgot to add the following sentences.

Thank you very much.

The hot dog is so gross because it is filled (stuffed?) with ketchup and mustard.
2) He is wearing a two-color V-necked T-shirt and probably a pair of jeans.
3) Storm is sitting on a table near him. She is observing him eating. She is wearing her (died red) hair tied at the back. She has a lot of jewellery on: a chain of beads (?), a necklace with a pendant and lots of bracelets around her right wrist.
