i've been asked to do a cake like the picture below which i can but can someone tell me how to do the baby carriage? whats it made of fondant or sugar mold?how can i do something similar?

If you look at my pics I made a bassinet this weekend a little bigger I made it out of rice krispy

Could you use one of the larger plastic easter eggs as a mold and make it out of fondant?

I tried doing just fondant it didn't hold up very well I used a small egg shape pan it was a little to small so I ended up using the small oval pan

It's hard to tell from the pic but it could be a sugar molded egg or you could use gp (mixed w/fondant). I'm guessing fondant or gp. Sugar molding was used mainly before gp caught on
A sugar mold or gp will hold up fine as would fondant w/Tylose added.

In the Wilton Tiered Cakes Book page 46 there is the cutest baby carriage on top of a tiered cake and one of my students made it. The egg pan is what they used and a mix of fondant and gumpaste to mold in that shape. It gives step by step instructions. The carriage is "balanced" on lollipop sticks and the wheels are either cookies or fondant.

Good luck!

what if i don't have an egg shaped mold what can i use instead?

I would suggest a piece of foam cut and covered with a thin layer of fondant for the base of the bassinet
