① Mattel Fisher-Price ⭐︎Push and Go! Truck Monster Green⭐︎ Push the monster's head and let go, and the monster will start running! Children naturally learn about cause and effect. By making the monster move forward, it encourages your child to chase after it and crawl. ② O'ball ⭐︎Wobble Bobble⭐︎ When you turn on the switch and shake or tap the ball, it vibrates and makes fun sounds. My child was quite fond of this one. ③ Kids2 Bright Starts ⭐︎Funny Fishbowl⭐︎ A toy shaped like a fishbowl. When you press the fish, it plays a fun melody and colorful balls spin and fall out. Chasing and picking up the popped-out balls develops the baby's motor skills. Items ② and ③ are battery-operated and have been tested to work. These colorful items can be enjoyed for a long time, from the crawling and sitting-up stages. This is an educational toy set that stimulates a baby's curiosity. The reactions are very cute. There is no noticeable damage, but these items have been used by a child and stored at home. For those who understand.
