Fulfill demands of Tom and his friends to complete activities. Tap on the speech bubble that appears above a character.  
You will find different icons in each speech bubble. These icons pertain to a particular activity. Tap on an icon and the character will move closer to an object that’s connected with that activity. Tap on the object or drag and drop the character onto the object to start an activity.  
For example, if you tap on the spoon and fork icon above Angela, it means she is hungry. Just tap on it and she will be on the dining table. Now tap on the spoon and fork icon above the food bowl and drag and drop delish food items to feed her.  
When Tom and his friends perform certain activities, such as playing a sport, conversing with a friend, playing an indoor game, singing etc. You will get bus tokens and stars upon completion. Just tap and hold a character and drag him/her towards a toy or a certain object to begin performing an activity.
Tap on Bubbles to get Your Rewards
When an activity ends, rewards appear inside transparent bubbles. Tap on bubbles to collect your rewards.  
Stars fill the star meter (more on this later) and bus tokens are used to fill the bus stop sign board located on the street.  
When the sign board fills up, just drag one of the characters onto the bus. You will be taken to a trip to the nearby supermarket, where you can get lots of goody bags that may contain toys/games and costumes. You may also obtain important items, such as healing items for the medicine cabinet and food.
