bulged out

• She was a big one , and she was coming in a hurry , too , looking like a black cloud with rows of glow - worms around it ; but all of a sudden she bulged out , big and scary , with a long row of wide - open furnace doors shining like red - hot teeth , and her monstrous bows and guards hanging right over us
  这可是一条大轮，正急匆匆地开过来，看上去活象一大片乌黑乌黑的云，四周围亮着一排排萤火虫似的亮光，可是一刹那间，它突然露出了它庞然大物的凶相，但见一长排敞得开开的炉门，一闪闪发着红光，仿佛红得炽热的一排排牙，它那大得吓人的船头和护拦装置直接罩住了我们。
