There are two kinds of activities – Basic and fun. The latter lets you play with toys, games and engage in various hobbies such as singing and playing the electric guitar. Activity icons appears as speech bubbles above a character.
Completing the following basic activities doesn’t grant rewards:
– Eating food (Appears as fork and spoon in the speech bubble above a character)
– Going to the Loo (Flush toilet)
– Taking medicines (Big Plus sign)
– Bathing in the bath tub (Shower)
– Sleeping (Crescent Moon)
However, you will have to complete the above tasks (in case they appear as speech bubbles above a character) if you want Tom and his buddies to perform other tasks. You just can’t drag a character to a toy or game if he/she demands food or wants to go to the loo. They will flat-out refuse to perform any other task until you have completed their basic tasks as shown on their speech bubbles.
Any speech bubble that does not have the above basic activity icons grant some kind of a rewards, such as stars or bus tokens.
A speech bubble above a character can have a guitar icon, a board game icon, washing machine, bath tub, teddy bear etc. All these activities grant some kind of reward after completion. You just have to tap on such an icon to move your character closer to that object and then drag and drop that character over the object to start the activity.
