**Q: Is a manual included? The box implies the instructions are only available online, & I'd rather not print out 50+ color pages . . .**
A: The instructions for 42073 BASH! are included, but the instructions to combine this item with 42072 WHACK! to create WHACK! 'N' BASH! are only available online

**Q: What to do if package was damaged when received?**
A: Return to Amazon for a replacement.

**Q: Is this tough enough for 13 yr old boy to play with after building?**
A: I think it would be as long as they are not overly aggressive with it. However, we bought it for my at the time 6 yr old and my 10 year old helped him put together. I don’t know how much enjoyment a 13yo will get out of it.
